What is the test for a defendant to challenge as vindictive a prosecutorial decision to increase the severity of criminal charges following a successful appeal?

If the defendant challenges as vindictive a prosecutorial decision to increase the number or severity of charges following a successful appeal, the court must examine the prosecutor's actions in the context of the entire proceedings. If any objective event or combination of events in those proceedings should indicate to a reasonable minded defendant that the prosecutor's decision to increase the severity of charges was motivated by some purpose other than a vindictive desire to deter or punish appeals, no presumption of vindictiveness is created. (United States v. Krezdorn , supra , 718 F.2d at pp. 13641365.)
