OPINION AND ORDER
SHIRA A. SCHEINDLIN, District Judge:

I. INTRODUCTION
Over fifteen thousand current and former New York City police officers and detectives ("plaintiffs") assert that the City *557 of New York and the New York City Police Department ("NYPD") (collectively "defendants") systematically violate plaintiffs' overtime rights under the Fair Labor Standards Act ("FLSA").[1] The Court has scheduled a trial for November 3, 2008. In anticipation of that trial, plaintiffs have made three motions in limine, which defendants oppose. Defendants have made five motions in limine, and plaintiffs oppose three of them. Each parties' disputed motions are separately discussed below.

II. APPLICABLE LAW
The Federal Rules of Evidence favor the admission of all relevant evidence.[2] Evidence is relevant if it has "any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence."[3] A district court will "exclude evidence on a motion in limine only when the evidence is clearly inadmissible on all potential grounds."[4] "Indeed, courts considering a motion in limine may reserve judgment until trial, so that the motion is placed in the appropriate factual context."[5] Moreover, a court's ruling regarding a motion in limine "`is subject to change when the case unfolds.... Indeed even if nothing unexpected happens at trial, the district judge is free, in the exercise of sound judicial discretion, to alter a previous in limine ruling.'"[6]

III. DISCUSSION

A. Plaintiffs' Motions in Limine
Plaintiffs have filed three motions in limine seeking to preclude defendants from 1) arguing that plaintiffs' FLSA claims are attempts to circumvent their collective bargaining agreements ("CBAs"),[7] 2) offering the expert testimony of statistician Christopher Erath,[8] and 3) using the jointly-conducted survey of plaintiffs in argument or as evidence at trial.[9]

1. Circumvention of Collective Bargaining Agreements
Plaintiffs move in limine "to preclude defendants from describing FLSA overtime as overtime beyond that for which plaintiffs have collectively bargained."[10] Specifically, plaintiffs aim to prevent counsel for the City of New York from repeating statements made in a previous FLSA trialMullins v. City of New York[11]that they feel were unfairly prejudicial *558 and "invite[d] jury nullification."[12] Counsel for the defendants stated during the Mullins trial that plaintiffs in that case wanted "`more overtime beyond what they bargained for'" and that they were "`not entitled to this extra overtime.'"[13]
"Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence."[14] This Court has "broad discretion under Rule 403 to balance the probative value of evidence against the risk of prejudice."[15]
To the extent that FLSA requires greater compensation than plaintiffs' contractual overtime payments, statutory overtime is by definition "beyond that for which plaintiffs have collectively bargained." Defendants did not suggest in the Mullins trial that plaintiffs could never be entitled to statutory overtime on top of contractual overtime; nor would they be permitted to make such a statement in this case, as it would be flatly contrary to law.[16] To the extent that this argument is implied by the statements at issue, the probative value of explaining the difference between contractual and statutory overtime outweighs the risk of prejudice. Plaintiffs' motion is denied.

2. Expert Testimony of Christopher Erath
Plaintiffs next move "to preclude defendants from proffering the expert opinion of Christopher Erath regarding whether the NYPD enforces a cap on cash overtime."[17] Plaintiffs base this motion on defendants' failure to provide the specific regression equation used by Erath in formulating his expert report,[18] as well as several complaints about the process by which Erath developed his analysis.[19] However, Erath's expert report provides the variable sets for the two regression analyses he performed.[20]
The court serves an essential gatekeeping function concerning technical testimony and may use the factors set forth in Daubert v. Merrell Dow Pharmaceuticals to assist in this determination.[21] A district court has "broad latitude when it decides how to determine [the] reliability" of technical testimony.[22]
*559 Plaintiffs focus on whether Erath's theory or technique "can be (and has been) tested."[23] Because Erath has identified the variables he used, derivation of his regression equations is as simple as filling out a form.[24] Erath's theory has been tested, and it can be reproduced by plaintiffs. Nor do plaintiffs' other concerns merit exclusion of Erath's report. First, while Erath did not expressly note that his result was statistically significant or provide variance statistics, this issue can be addressed on cross-examination.[25]Second, Erath's failure to include other variables that might have influenced the number of overtime hours does not invalidate his conclusion vis-à-vis the single tested variable, particularly when defendants are attempting to disprove that a particular variable violation of an alleged caphas any effect at all.[26] Whether Erath's model is the best possible model may again be the subject of cross-examination. Third, although Erath tailored his data set to exclude certain officers who did not work nearly enough overtime to approach the alleged cap, his approach consistently tested the same hypothesis. Removing irrelevant data pointsthose officers nowhere near the alleged capdoes not interfere with testing whether the violation of the alleged cap had any effect on the amount of overtime available in later work periods.[27]
Erath's failure to record the panoply of descriptive figures displayed automatically by his statistics program does not constitute best practices for preparation of an expert report. Nevertheless, his report does contain the "the data or other information" he considered in forming his opinionas required by Rule 26[28]and his anticipated testimony satisfies the minimal requirements of Rule 702. Moreover, the probative value of his analysis outweighs any risk of prejudice or confusion it creates. Plaintiffs' motion is denied.

3. Use of the SRBI Survey
Plaintiffs also move in limine "to preclude defendants from introducing evidence or argument relating to the survey of plaintiffs conducted last fall by Schulman, Oronca & Bucuvalas ("SRBI")."[29] Specifically, plaintiffs argue that since defendants *560 did not designate a survey expert as a trial witness in their initial pre-trial disclosures, defendants may not present evidence concerning the jointly-conducted survey of the plaintiff class.[30] Defendants claim that an expert is unnecessary[31] or in the alternativethat if plaintiffs wish to question the methodology of the survey, it is plaintiffs who must call an expert witness.[32]
The survey in this case was jointly developed by the parties and administered by a neutral third-party survey firm, SRBI.[33] The parties engaged in negotiations over the language, structure, and administration of the survey with the help of Magistrate Judge Theodore Katz,[34] and the survey went through multiple pretests in order to insure its usefulness and statistical validity.[35] Despite their attempts now to discredit it, plaintiffs previously submitted to this Court the declaration of Thomas M. Guterbocka survey expert who expounded upon the methodology, neutrality, and reliability of the survey.[36]
The Manual for Complex Litigation lays out basic parameters for reliable surveys, including both conformance with recognized statistical standards and survey construction likely to elicit impartial answers.[37] The Manual notes that evidence of proper survey construction "ordinarily involve[s] expert testimony" and that parties should raise objections promptly to ensure that "corrective measures [can be] taken before the survey is completed."[38] Although, the Manual notes that complex statistical evidence "should be presented at trial through summaries, charts, and other tabulations," it does not suggest that expert testimony is necessary to present the outcome of a survey to the jury.[39]
Under Rule 26, "a party must disclose to the other parties the identity of any witness it may use at trial to present evidence under [the Federal Rules of Evidence governing expert testimony]."[40] Expert disclosures are mandatory, and a Court may impose sanctions for failure to *561 make them.[41] However, a Court may also simply order that a party supplement or correct insufficient disclosures.[42] Similarly, Rule 26 requires the disclosure of most expert witnesses to be accompanied by a written report containing six specific elements.[43] However, this requirement is waived if the witness is not "retained or specially employed to provide expert testimony in the case or one whose duties as the party's employee regularly involve giving expert testimony."[44]
The survey in this case is sufficiently complex to warrant an expert witness to establish a foundation and to respond to challenges concerning the survey's construction and validity. Defendants did not name a survey expert in their Rule 26 disclosures; nor did they submit an expert report concerning survey evidence. However, this does not entirely preclude introduction of evidence concerning the SRBI survey at trial. Defendants may amend their Rule 26 disclosures to include an employee of SRBI as an expert witness. SRBI is capable of describing the technical aspects of the survey data, including variation in the confidence intervals among questions and the effect of limiting the time period addressed by the survey. Moreover, because both parties played an active role in the survey development process and have had equal, albeit restricted access to SRBI during this litigation, the purpose of the notice provision is not thwarted by allowing a late amendment in these unique circumstances. On the other hand, defendants may not call their retained survey expertEugene Erickson as an expert witness; plaintiffs rightly protest that they have been denied sufficient notice of his proposed testimony.[45]
Moreover, Rule 26 does not require the SRBI employee who defendants choose to name to submit a formal expert report.[46] As plaintiffs note, "the parties employed [SRBI] as a third-party survey administrator,"[47] Therefore, no SRBI employee was "retained or specially employed to provide expert testimony in the case."[48] Nor are plaintiffs harmed by the lack of an expert report here. The purpose of an expert report"to provide the opposing party with the scope of the opinion that will be provided at trial, to allow for an effective cross examination of the witness, and to limit the total number of depositions"[49] is fulfilled by SRBI's final report. The report provides frequency charts for each question asked in the survey,[50] and both parties have also had access to raw data developed by the survey.[51] Moreover, the *562 probative value of the survey results outweighs the risk of prejudice introduced by presentation of survey evidence by an SRBI employee. Plaintiffs' motion is denied.

B. Defendants' Motions in Limine
Defendants have filed five motions in limine seeking to preclude plaintiffs from 1) offering the expert testimony of John Eterno concerning social scientific explanations of police practices, 2) entering expert reports into evidence, 3) entering newspaper articles into evidence, 4) offering the testimony of plaintiffs who failed to meet discovery obligations, and 5) offering "common knowledge" testimony concerning unofficial police practices.[52] Moreover, as alternative relief on their fourth motion, defendants move to dismiss the claims of the fifty-seven plaintiffs who failed to meet discovery obligations and for an adverse inference instruction concerning the evidence that defaulting plaintiffs would have provided.[53] Because the parties have resolved defendants' second and third motions,[54] I need only address the remaining three.

1. Expert Testimony of John Eterno
Defendants' first motion in limine asks this Court to "[p]reclude the report and testimony of [p]laintiffs' expert witness John Eterno."[55] Defendants argue that Eterno's opinions fail to satisfy the requirements for expert testimony set forth in Rule 702 of the Federal Rules of Evidence and that he is barred from offering paid testimony by conflict of interest provisions in the New York City Charter. Plaintiffs respond that Eterno's testimony will provide specialized knowledge concerning police management practices based on a foundation of academic study and first-hand observations of the NYPD.[56]
An expert witness may offer "scientific, technical, or other specialized knowledge" to assist the trier of fact.[57] Permissible experts are not limited to specialists in the hard sciences and mathematical disciplines; they include authorities in "industrial psychology"[58] and "police management."[59]
Eterno's proposed testimony addresses important elements of plaintiffs' case. Specifically, Eterno will testify concerning the NYPD's "personnel management strategy" and "the formal and informal techniques the Department uses to control officers' behavior."[60] Given that plaintiffs *563 hope to establish numerically-based personnel rules such as a cap on cash overtime and denials of compensatory time as punishment for failing to meet other quantitative goals, such argumentsif credited by the jurywill lend credence to their claims.
To the extent that Eterno bases his testimony on the wealth of social science literature concerning organizational theory generally and police management in particular, the testimony will be typical of an academic expert.[61] Moreover, to the extent that Eterno bases his testimony on personal observations made in a lengthy career at the NYPD, he may testify as an expert in industry practices, a common occurrence in civil litigation.
However, the Second Circuit recently cautioned that experts must not cross the "increasingly thinning line" between legitimate use of expert opinion to explain complex or esoteric subjects and "substitution of expert opinion for factual evidence."[62] Therefore Eterno may only testify "concern[ing] matters that the average juror is not capable of understanding on his or her own."[63] Moreover, although experts "`can testify to opinions based on hearsay or other inadmissible evidence,'" they may only do so "`if experts in the field reasonably rely on such evidence in forming their opinions.'"[64] While "organizational studies" does not always lend itself to experimentation and use of the scientific method, experts must still rely on verifiable citations to establish empirical facts. Accordingly, Eterno may not testify as to unsubstantiated opinions or personal knowledge based on unidentifiable sources.[65] Numerous examples of such "common knowledge" assertions are found in Eterno's expert report,[66] and they are hereby precluded.
Defendants also argue that Eterno is barred from testifying by two conflict of interest provisions of the New York City Charter. Section 2604(d)(4) states:
No person who has served as a public servant shall ... receive compensation for any services rendered, in relation to any particular matter involving the same party or parties with respect to which particular matter such person had participated personally and substantially as a public servant through decision, approval, recommendation, investigation or other similar activities.
Similarly, section 2604(d)(5) states:
No public servant shall, after leaving city service, disclose or use for private advantage any confidential information gained from public service which is not otherwise made available to the public; provided, however, that this shall not prohibit any public servant from disclosing any information concerning conduct *564 which the public servant knows or reasonably believes to involve waste, inefficiency, corruption, criminal activity or conflict of interest.
The purpose on these provisions is "`to prevent public servants from exploiting public office for personal gain, subordinating the interests of the City to those of a prospective employer, or exerting special influence on government decision-making.'"[67]
Testimony of a former city employee concerning possible statutory violations by city agencies is not the type of conduct that the Charter provisions aim to prevent. With regard to the first provision, Eterno did not work on the particular matter at issue, a dispute concerning the overtime policies of the NYPD.[68] Nor did the matter involve the same parties with whom he worked as a public servant, as that provision must be construed logicallyas an anti-corruption provisionnot to include the City itself. With regard to the second provision, Eterno is barred only from disclosure of confidential information, as mere statutory violations are not one of the categories of inquiry excluded from the rule. Nevertheless, the provision does not bar non-confidential testimony from an individual previously exposed to confidential matters.[69] Defendants' motion to preclude Eterno's testimony is granted in part and denied in part.

2. Plaintiffs Who Have Failed to Provide Discovery
Defendants next move in limine to "preclude evidence relating to [fifty-seven] opt-in plaintiffs who failed to meet their discovery obligations, ignored various court orders by failing to appear for their noticed deposition and/or failed to respond to [d]efendants' discovery requests."[70] Plaintiffs have responded by agreeing "not to call these [non-compliant] Representative Plaintiffs as witnesses at trial,"[71] but they resist defendants' call for harsher remedies, including dismissal of those plaintiffs' claims and issuance of an adverse inference instruction concerning information that might have come to light had plaintiffs been fully compliant with discovery obligations.[72]
Dismissal under Rule 41(b) for failure to comply with a court order is governed by five factors:
[1] the duration of the plaintiff's failures, [2] whether plaintiff had received notice that further delays would result in dismissal, [3] whether the defendant is likely to be prejudiced by further delay, [4] whether the district judge has taken care to strike the balance between alleviating court calendar congestion and protecting a party's right to due process and a fair chance to be heard, and [5] *565 whether the judge has adequately assessed the efficacy of lesser sanctions.[73]
This Court has wide discretion concerning whether and to what extent to impose sanctions related to a failure to abide by discovery orders.[74]
The five factors weigh in favor of a more moderate sanction than outright dismissal Although these plaintiffs were ordered to produce documents within two weeks at a status conference more than six month's ago, this Court denied defendants' request for an order to show cause that would have expressly warned plaintiffs that their claims would be dismissed if they failed to comply.[75] Moreover, defendants have received voluminous discovery such that these plaintiffs' failure to produce documents will not severely prejudice their case. Dismissal of fifty-seven plaintiffs among 16,000 would not alleviate court congestion, and lesser sanctions will adequately address this issue. The motion to dismiss the claims of the fifty-seven non-compliant plaintiffs is denied. Moreover, those plaintiffs may offer evidence of damages, as preclusion of such proof would be tantamount to dismissal.
A party seeking an adverse inference must show
(1) that the party having control over the evidence had an obligation to timely produce it; (2) that the party that failed to timely produce the evidence had `a culpable state of mind'; and (3) that the missing evidence is `relevant' to the party's claim or defense such that a reasonable trier of fact could find that it would support that claim or defense.[76]
This court has "broad discretion" concerning whether to issue an adverse inference in response to a "breach of discovery obligation."[77]
Here forty-five of the 250 randomly selected plaintiffs failed to comply with an order that they produce the memo-books in which they log their hours.[78] There is no doubt that plaintiffs had control over the memo-books and an obligation to produce them. Moreover, the threshold for a finding of a "culpable state of mind" is quite low. "`It makes little difference to the party victimized by the [failure to produce] evidence whether that act was done willfully or negligently,'" and it follows that such distinctions make little difference to the Court as well.[79] Here the Court repeatedly directed select plaintiffs to produce the memo-books and issued pellucid warnings that failure to comply with discovery orders would bear consequences.[80] Therefore, the second factor is met as well. However, the memo books are of limited relevance to the claims remaining in this case. The principal evidence contained in the memo books relates to an officer's *566 notations regarding breaks from work[81] Because this Court has rejected defendants' meal period defense,[82] the questions of whether officers take breaks and how long those breaks last are no longer at issue. Therefore, although I am disturbed by certain plaintiffs' insubordination in the face of court orders, there is no need for an adverse inference instruction concerning non-production of the memo books.
Similarly, no adverse inference instruction is necessary concerning plaintiffs who failed to appear for noticed depositions. Plaintiffs' self-imposed sanction of declining to list any of the non-compliant plaintiffs as witnesses for trial provides an adequate penalty. Moreover, defendants' rejection of some plaintiffs' attempts to reschedule depositions after the discovery cutoff negates proof of plaintiffs' culpable state of mind.[83] Defendants' motion is granted in part and denied in part.[84]

3. Common Knowledge Testimony
Defendants' final motion in limine seeks to preclude what they describe as "hearsay evidence relating to an alleged `cap' on cash overtime based on alleged `common knowledge' within the NYPD."[85] Plaintiffs respond that such testimony is an officer's personal knowledge that he or she has acquired by "[t]alking with other people."[86]
"`Hearsay' is a statement, other than one made by the declarant while testifying at the trial or hearing, offered in evidence to prove the truth of the matter asserted."[87] Hearsay testimony is inadmissible unless it is subject to one of numerous exclusions or exemptions.[88] No such exemption or exclusion exists for "common knowledge" testimony. Nor may hearsay become personal knowledge merely because a witness has internalized statements made by others and decided they must be true. Even if a witness attests that she has received the same information from numerous sources, it does not overcome the fundamental notion that the witness is repeating the content of out-of-court statements. Unattributed out-of-court statements also cannot be offered in court to build a foundation for testimony that relies on no other source. This formulation merely rephrases the hearsay rule.
The parties do not contest that out-of-court statements by commanding officers confirming particular NYPD policies are categorized as non-hearsay because they are admissions by a party opponent.[89] Therefore such evidence is admissible. In all other respects, an attestation of "common knowledge" is in fact "no evidence" at all.[90] Defendants' motion is granted.

IV. CONCLUSION
For the reasons set forth above, plaintiffs' motions in limine are denied. Defendants' motions in limine are granted in *567 part and denied in part. The Clerk of the Court is directed to close these motions (Docket Nos. 218, 220, 221, and 222).

[25]  A trained statistician would not indicate a definitive resultas Erath did in his report unless it were statistically significant. See, e.g., David S. Moore & George P. McCabe, Introduction to the Practice of Statistics 461-66 (4th ed. 2003). Moreover, regression using as few variables and as many data points as the analysis here is extremely likely to have produced a statistically significant result, revealing either a positive or a negative correlation. See, e.g., Steven P. Segal, Large Data Sets Are Powerful, 54 Psychiatric Servs. 745 (2003).
[26]  Cf. In re Wireless Tel. Sere. Antitrust Litig., 385 F.Supp.2d 403 (S.D.N.Y.2005) (rejecting analysis in support of a single-factor explanation that failed to take into account alternative variables).
[27]  While plaintiffs refer to the elimination of certain data points as running "at least six different regression equations," Pl. Erath Reply at 1, in fact the analysis described applies the same equation to several data sets. Therefore, contrary to plaintiffs' argument, Erath did not attempt to find a theory that supported his preferred result; he merely attempted to remove static. Nor is such experimentation necessarily impermissible. A statistician may fall upon a model that explains a great deal of the variation in a particular data set just as the apple apocryphally fell upon Newton.
