Before LANDAU, Presiding Judge, and BREWER, Chief Judge, and HASELTON, Judge.
BREWER, C.J.
This case is before us on remand from the Supreme Court, which vacated our prior decision, State v. Jackson, 201 Or.App. 208, 117 P.3d 315 (Jackson I), in light of State v. Ramirez, 343 Or. 505, 173 P.3d 817 (2007), adh'd to as modified on recons., 344 Or. 195, 179 P.3d 673 (2008), and State v. Fults, 343 Or. 515, 173 P.3d 822 (2007). State v. Jackson, 345 Or. 315, 195 P.3d 63 (2008). In Jackson I, we vacated defendant's sentences and remanded for resentencing because the trial court had imposed a departure sentence based on judicial findings. That factfinding constituted plain error, and we exercised our discretion to correct it. The issue before us on remand is whether, in light of Ramirez and Fults, we properly exercised our discretion under Ailes v. Portland Meadows, Inc., 312 Or. 376, 381-82, 823 P.2d 956 (1991). We conclude that our exercise of discretion in Jackson I was erroneous. Accordingly, we affirm.
Defendant was convicted of one count of second-degree robbery and one count of third-degree robbery. On the second-degree robbery conviction, the trial court imposed a durational departure sentence of 102 months' imprisonment. The court imposed that sentence because "defendant [was] on supervision *100 at time of incident and persistent involvement."
In this case, the trial court did not explicitly state that it was relying on the departure factors it found either singly or in combination, and therefore we assume that the court did not consider each factor to be independently sufficient to support a departure. State v. Wilson, 111 Or.App. 147, 826 P.2d 1010 (1992). Thus, remand for resentencing may be warranted if either one of the factors relied on by the trial court is subject to legitimate debate. See Ramirez, 343 Or. at 513, 173 P.3d 817 (setting out "legitimate debate" standard for exercise of discretion to review unpreserved challenges to departure sentences based on judicial findings of fact).
We first examine the departure factor of defendant's supervision status at the time he committed his current offenses. As we explained in State v. Allen, 198 Or.App. 392, 396, 108 P.3d 651, adh'd to as clarified on recons., 202 Or.App. 565, 123 P.3d 331 (2005), rev. den., 342 Or. 46, 148 P.3d 915 (2006), an upward departure sentence based on a defendant's supervisory status "requires further inferences about the malevolent quality of the offender and the failure of his [supervisory] status to serve as an effective deterrent." In this case, defendant had an extensive criminal history, which included parole violations in 1975, 1979, 1983, 1985, 2000, and 2002. That evidence was uncontroverted, and, in our view, removes all legitimate debate that the jury would have drawn the inference that defendant had failed to be deterred by his supervisory status.
With regard to the departure factor of defendant's persistent involvement in similar offenses, as we explained in State v. Williams, 225 Or.App. 325, 328-29, 201 P.3d 267 (2009), under State v. Bray, 342 Or. 711, 724, 160 P.3d 983 (2007), there is no legitimate debate that a jury would have found a defendant to have been persistently involved in similar offenses where the number and frequency of the defendant's prior convictions compels the inference that his or her criminal behavior has been "persistent." Here, defendant had convictions for armed robbery (1971); first-degree robbery (1972 and 1973); two burglaries (1976); felon in possession of a firearm (1979 and 1983); bank robbery (1985); use of a weapon (1988); unlawful weapons possession (1989); and robbery (1991). Defendant committed his current offenses in 2003, but the state presented uncontroverted evidence that, between 1991 and 2001, defendant was incarcerated in a federal prison for his 1985 bank robbery conviction. Defendant was released on federal parole in 2001, violated his parole, and was re-released in 2002. On this record, we conclude that there is no legitimate debate that the jury would have drawn the inferences required by Bray. Accordingly, we decline to exercise our discretion to review the assigned error.
Affirmed.
