I would say it works so well because the US population is huge and relatively wealthy. The US has 318 million, UK has 66 million, Canada 33 million, pretty apparent that the bigger the population the better chance you have of fielding a winning team every time, especially when there is money to fund it.
My fault with the system is the apparent lack of clarity. The actual system is fine, though coaches could be given better guidelines to help them filter gymnasts who are suited to the process.
I think that coach education is key and when I first wandered in to a US gym 16 years ago I was very surprised to discover that there was no real coach education system. This clearly is changing and evolving.
Well, exactly. Maybe it's just population but we don't have a higher population than China. Anyway, obviously before a vast shift and growth in USA Gymnastics over the past 3 decades or so we weren't having these results.
The system we have in place now has a big emphasis on raw talent identification. The idea is to identify kids with talent that could be developed with the support of the National Team staff, not necessarily to just identify kids who are already 100% ready for elite (because by then it would cut a lot of kids out). The early iteration of this was the first version of TOPs, and since then many things have changed with an emphasis on skill development as well. Even when kids aren't in the program they are identified and brought into the development system when NT staff sees potential. Trinity Thomas was spotted at a meet and invited to the ranch and later qualified Jr Elite.
So that is why it would run counter to their goals to say kids have to have a certain result before they ever get on the radar of the NT staff. Even when a kid might not have a good result at a qualifier, if that kid is really talented but just wasn't prepared, the NT staff might still be interested. If she is really good but messed up a few times at TOPs national testing, again, they want to have a system in place where they can see her again.
As far as some of it being a moneymaker, I agree, it definitely is. Like any level of the sport, those at the bottom of the pyramid are propping up the top, so to speak. But I don't know if that's any secret and I don't really know any way around that because we need money to fund the program - it's not funded by our government like in some places. So that's just the way it is in all levels and all programs of USA Gymnastics.
