First, since the decision is for next fall just see how things go for now. Next fall all the routines will be changing, level 4, will be equivalent to level 5 this year, so I assume there will be no mill circle. She will also need her kips. Also I saw you have to be a 7yr old to compete in the new level 4 next year, so the ages are going up a year. I feel competing level 4 provided a very positive experience for my child. There is a lot to learn competing, especially how to function under stress, win and lose gracefully, etc... Also the judges get to know you child, and the child sees familiar faces judging. We also learned the fine things needed to get those scores up. Skills are one thing, just about everyone who competes have them, it is the small things in form, like where your feet need to be turned out, tightness etc.. that separate the winners, the 38s from the 36s. It takes time to learn those and do them without thinking in a routine. Personally I don't think anything she did in level 4 (except for the mill circle) was a waste of time.
