I will sorely regret chiming in on this, but two points on stats.
1. Kids at the PeeWee / Bantam age level are notoriously inconsistent.
2. Good statistical analysis needs sufficient sample size to be useful. The 'any given Sunday' rule.
Bantam Wave 3 played a total of 50 games last year at A, AA and AAA levelS (36/11/3). That's a decent sample size.
But these short tournaments for example are not enought. You get into Denver late and have the 7 am game with the altitude, time difference... you're probably going to lose your first game. Is that representative of your team?
My point is (and I'm a big fan of CORSI etc.) especially at this age, stats are a tool, but 'hockey sense' and experience is a more important tool.
That said, CAHA/SCAHA is so effed up I would be open to considering a relegation system like in soccer. Everyone plays a Labor Day tournament and gets their Tier set based on the results. Better for a team to move down then spend a whole season getting slaughtered, IMHO. Or moved up, to play at a more competitive level.
Discuss amongst yourselves. It's not perfect, but it ain't perfect now, either.
