My daughter will be competing level 7 this year. She was pretty good at lower levels, but not dynamite. We have been told that the coaches believe she will shine at L7 because she won't be doing cookie cutter routines. She is good on bars, beam, and vault, but just ok on floor. She is a great tumbler, but not a natural dancer. She is extemely flexible. The thought is that she can show off her strengths at the optional level. Anyone else experience this?
It's not a standard, but it happens. The skills in the compulsory routines are easy enough that a high percentage of kids will have polished routines, compete them well, and suffer only the occasional fall. That creates a situation where a fairly talented kid may not shine because there's nothing but shine surrounding her, well sorta.
Level 7 work is more demanding and tends to expose each childs weakest event, but allows them to use their best event to rise above the rest of their peers. More than that is the increased difficulty of the skills and the event requirements. Marginal kids are forced to find ways of fulfilling requirements, but kids that learn skills more easily can quickly adapt (relatively speaking) and go beyond that....... and that builds confidence and a sense of purpose that drives them to polish their routines and compete well.
Another factor is the way some, if not many, clubs will put kids that aren't completely invested in the sport onto their teams. These kids who blindly believe they can "have it all" and mix gymnastics with other activities as well as doing little else to help make their gymnastics time as effective as it can be. Sure, they're all dedicated and work hard, but they'll miss the occasional practice, come in with insufficient rest, or are supported by parents that are "iffy" about the sport. Sadly for them it takes more dedication and sense of immersion at the optional level and these kids tend to struggle at meets..... or just get by. Sad thing too, because some of them could be great gymnasts, or soccer players, track athletes, or amazing scholars.
So no, it's not a standard, but it happens quite a bit.
