The bat manufacturers are likely designing their bats, e.g. the design parameters which go into the trampoline effect, for bat speeds obtained by HS/College kids so when a smaller kid with bat speeds below that hits she is hitting off-design. That is also why getting the greatest bat in the world for a 75 lb kid is probably a waste of money..I think a better way to frame this would be "If some certain percentage of exit velocity is due to bat compression (trampoline effect?), is a larger percentage of THAT percentage due to the pitched ball at younger ages than it is at older ages". I would assume the answer is yes, although I don't know that there is a good way to determine that.
