There definitely is a critical mass after which more kids doesn't make any difference. What is this critical number? It would be different for different tactics. If you were talking about them jumping on you and doing whatever, there's only room for so many of them to jump on you. If you're talking about them forming en masse and bumrushing you, then the number is different. You could say that 100 kids running at you is a lot of mass, but when it hits you, it's certainly not with 100 times the force of one kid running into you.

I think anything more than single digits for either of these scenarios is all the same in the immediate. Any more than that just adds to the stamina and recovery ability required to keep repeating.
