What is the test for setting aside a sentence for a defendant who has pleaded guilty to a charge of possession of a drug with intent to pervert the course of justice?

However, where a "trial court has given both proper and improper reasons for a sentence choice, a reviewing court will set aside the sentence only if it is reasonably probable that the trial court would have chosen a lesser sentence had it known that some of its reasons were improper." (People v. Price (1991) 1 Cal.4th 324, 492, superseded by statute as stated in People v. Hinks (1997) 58 Cal.App.4th 1157; People v. Avalos (1984) 37 Cal.3d 216, 233.) Relevant to this case, rule 4.421(a)(7) states that the trial court may consider the fact a defendant "was convicted of other crimes for which consecutive sentences could have been imposed but for which concurrent sentences are being imposed."
