Bottom Line is when they started adding all these sub divisions of these levels whether it's called upper or lower, american or national, premier or elite, etc
Years ago there were 3 levels. Here on the east coast it was AA, A, B. In mid west they called it AAA, AA, A. Regardless east coast AA teams played in Nationals against their AAA teams, Their AA was our A and their A was our B.
So basically there were 3 levels IMO the 3 levels should be referred to as Tier 1, Tier 2 and Tier 3 or AAA, AA, A however you slice it (nobody likes the letter B moniker anyway lol), BUT what the levels are called shouldn’t matter.
The top 25% should be elite level teams and players (AAA), mind you the %’s are approx based on the # of players in the district at that birthyear.
Bottom level (A) should be 25%, and the middle level (AA) should be 50%, which is the avg kid that plays hockey.
Not looking for an argument from anyone, just stating it worked better years ago and tweaking it a little for the modern day would make it work best.
