Maybe I need to take a closer look. It's indeed more complicated than that. For example if the battery is drained by 5% (StandbyBudgetPercent) *before* 12 hours, the system will go into hibernation. So the 20% drain (StandbyBudgetPercent * StandbyBudgetRefreshCount) can only occur if *less* than 5% is used in each of the four 12 hour (StandbyBudgetRefreshInterval) periods. In practice, my Windows 11 nearly always hibernates at some time during the night, i.e. 5% drain is reached before 12 hours have elapsed.
