9 meets to me is alot. This doesn't allow as much time to really work on higher level skills since prep for a meet means routine run throughs. This year my gymmie ended up doing 6 meets plus states. We don't have sectionals and the gym only does USAG( I don't think there is any AAU in the state). By that state meet, I think she was glad the season was over and could start working on her L8 stuff. We have a L9 who will compete at western sectionals and her mom wishes the season was over

As excited as this girl is about going to sectionals she is getting a little tired of practicting routines and has an ankle sprain that just has not been able to heal and won't until sectionals are over.
One way to look at it, is if your dd continues in gymnastics, the gym time goes up, money goes up and you don't want her suffering overuse injuries by the time she is L5. She has a big national meet and most kids in the traditional USAG system don't get to ever do a meet like that, so I would just let her practice with that goal in mind and forget the "additional" meet.
Our girls had 3 wks between their last "regular" meet and states. Seemed just the right amount of time to take it easy for 1 week and then build for 2 weeks. Most had their season best AA scores and now on to other things.
