The only exception to this was the one time I and another girl got switched for cheating, and there we each got four across the backside (over our undies, but with skirt and slip up) and an additional two, one across the back of each calf where it stung like nothing you’d ever believe. This was really quite formal, but I wouldn’t say there was any “limit” on how many cuts of the willow switch we’d get. If the principal figured we deserved six, that’s what she gave us, and if she figured we deserved more then I guess she’d have given them to us all at once. Fortunately for me, I never had to find that out where the switch was concerned, because six with that thing, especially those last two across the back of my calves, were six quite enough indeed, thank you, ma’am.
