"High school kids get to practice 5 days a week" Weak argument. Kids Club kids can practice 5 days a week if they want. In fact Kids Club kids can seek out any club/partner they want across the country to get better. There are way more restrictions on high school kids when to opportunities to get better.

When I was an 8th grader, the old man and I knew I would have some stiff high school competition at kids state. So he took me all over the place to get the best possible competition in the country and help prepare me to win a state title against high school competition. At the end of the State Tournament I was at the top of the podium and below me were 3 freshmen who had placed at high school state.

Moral of the story: If you think your competition is out working you then find opportunities that will help push you past your competition.
