When reviewing a challenge to the sufficiency of the evidence, what is the test for reversal of a finding of insufficient evidence?

When reviewing a challenge to the sufficiency of the evidence, we review the whole record in the light most favorable to the judgment to determine whether there is substantial evidence from which a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt. (People v. Stanley (1995) 10 Cal.4th 764, 792.) If the circumstances reasonably justify the trier of fact's findings, reversal is not warranted merely because the circumstances might also be reasonably reconciled with a contrary finding. (Id. at p. 793.)
