How about "progress more slowly than their teammates who attend more practices?" For me, I would have no problem with my DD taking more time for another sport, and her gym allows that in JO to some extent, particularly at the compulsory levels. My DD would definitely feel like she is falling behind with regards to her personal goals, though.
Yeah, no.
Each journey is unique..... And each gymnast progresses in their own time some of it is based on hours. Some of it just how the do mentally, some physically, some depends on staying healthy or not.
Daughters group mostly (past season) L4s going to Level 6
One girl in their group is L5 (past season) she is mostly a year ahead, but technically "behind" if you measure comparing to the girls I her old group going to L7.
Just looking at BHS on beam (which our gym requires for L6).
The L5 girl who has been training a year longer then the L4 girls still doesn't have it. I don't know why. Probably fear related.
Most of the rest of Level 4s have it.
Almost all our girls train 4 days a week, my daughter trains 3 (this past spring we added a 45 min weekly private, to offset the 3 hour Sat practice she can't be at during the school year)
Most of the girls also supplement their training with even more privates, we don't usually. I don't think the level 5 kid does either.
My daughter was 4th last to get her BHS, doing significantly less hours. Her bars skills tend to lag but she is doing OK. And she is a cautious gymmie, she is not usually the first to get skills even when they did the same hours. She is not in a rush.
Another kid was 2nd to last getting her BHS, but is is the youngest by far.
The L5 ahead a year will be the last but hopefully in time to go to 6 this season.
Another kid, she wouldn't do a squat on for L4 all year, she just got it last week yet has actually done Giants.
And three kids have moved on this summer. One was really starting to shine and they are onto other things.
These kids aren't ahead or behind. They are going at their own pace.
Can't speak for the rest of our group, but my daughter sets her own goals, what the other girls are doing just doesn't factor into her plan for herself.
Getting into these higher levels, I can see fear starting to be a factor. Injuries as well, we have had a few (my kid included). I can easily see a kid not moving up a level due to an injury. Or a kid who zoomed ahead getting stuck because if a block. And then the next thing you know that slow but steady kid, if they remain block and injury free. Or that kid with terrible form finally gets that straightened out. And then the pass the kids who were "ahead" .
The journeys are so unique and different. They get to where they are supposed be in their own time.
