It is way too early to give up on pitching if she enjoys it.
Looks like you have been reading the board about hello elbow. I would try to convert her when you have some time. If she is practicing 4 days a week I bet she does the transition to more IR fairly quickly.
She needs to be giving 100% on every pitch, including in practice. That might be what her PC is referring to. Not the amount of time is committing but not throwing at 100% all the time. Just a guess.
