My DD will be competing L7 this year, and if I was a betting person I would say it will likely go about the same as L4 and L5 did.... Very little or no podium time, and honestly that's ok with me. That's not what we're in the sport for. My kid has won an event ONE time. One. She was pretty consistently in the bottom scoring pack last year. She can do the skills, no problem there, she's usually one of the more advanced when it comes to actually getting/doing skills (always doing upgrades etc) but her form is just not there. She has a really easygoing personality, nothing type A about this one at all!
This year I thought for sure she was going to either repeat L5 (we don't do 6) or go Xcel, so did her coaches. She surprised all of us by working her buns off all summer and got all the L7 skills as one of the first ones. The other ones have caught up and will, in truth, probably score better than my DD because of her form. I'm still super proud of her and not considering holding her back because of that!!
All that to say I guess I don't see the big deal about scoring and placement as a measure of success. To me, if a gymnast is progressing well, learning new skills, competing where they are proficient (but maybe not experts) and having fun, then it's a successful season!!! Someone has to have the bottom scores too, those gymnasts might have an even MORE successful meet than the wunderkind gymmie who just won everything (as usual) but didn't really have to work for it on a personal level.....
I do get that some gymnasts feel that winning and scoring is really important and of course I was super thrilled for DD when she got called up for that ONE first place (and she was beaming ear to ear!) but I think as a whole we should celebrate personal successes more and placements less.
There really isn't any "repeating" of Optional levels, many kids simply do more years in each level once it gets to this point. Perfectly normal. Some kids will never get past L7-8 skills and even so, that's pretty amazing!!!
I would emphasize personal growth and progress even if it turns out she will do a second year at L7. In Optionals she can upgrade her skills in her routine as she goes. And, like others have said, a lot can happen in a short time. 11-12yo is a big time for personal development especially when it comes to emotional maturity and she may surprise you with her determination this upcoming year!
