I understand how frustrating this can be.
The best solution would be to find a good IR coach...but, not everyone lives near a major metro area like SoCal or Chicagoland. And, not everyone has the time or inclination to teach their DD how to pitch.
Although IR is important, there is more to pitching than IR. Lots of pitchers were taught HE and then change to IR. (Sydney Littlejohn is the current pitcher du jour, and here is her HE form from 5 or 6 years back...https://youtu.be/UwKUR5oMwCU. Somehow, her HE instruction didn't ruin her career.)
My "action plan matrix" would be:
1) Find a good IR coach.
2) If you can't do (1), then talk to the PC about it. See if you can convince your PC to either (a) teach IR or (b) leave your DD alone about HE or IR. Honestly, in these days of high speed cameras, proving the validity of IR should not be an issue.
3) If you can't do (1) or (2), then teach her yourself.
