You don't have to be a level 10 to do Hopes. It's a feeder program for younger gymnasts. They can still compete in the JO program.
It is a good point that many kids won't even make it to L10, regardless of their tracking. The last girl I know who skipped L5/6 quit after L7, similar to me but even more extreme. She was throwing up from stress at the meets. So it was better to move on, even though she had great physical talent. She found a team sport that was lower pressure for her due to the nature of it. Another girl didn't skip, but was very promising, and her parents were very into it. She too quit around L7 though, and wanted to do cheerleading (although this was kind of an issue of them moving and there were issues with the new gym). She eventually went back after years (and another move) and did L8 but she's certainly not going to be elite.
