What is the test for establishing a finding of guilty of perverting the course of justice?

"Simply establishing the court erred is not enough." (People v. Jefferson (2015) 238 Cal.App.4th 494, 508.) "[T]he erroneous admission of other crimes evidence is harmless if it does not appear reasonably probable that without the error a result more favorable to the defendant would have been reached." (Lopez, supra, 198 Cal.App.4th at p. 716.) As discussed above, the other evidence of appellant's intent was overwhelming. Further, the evidence connecting appellant to the charged crimes was sufficiently strong that it is not reasonably probable the trial court's error affected the verdict.
