If you think about it it really just evens out. While 321a and 4a have more schools, 5a and 6a have more kids in their schools. In my opinion, at the end of the year 4a will always have the most kids ranked. While 5a and 6a will always have the most topnotch kids and 321a will always be at the bottom of the heap (numbers wise). It changes from time to time with new schools being built and class changes. But numbers don't prove anything... Only wrestling does.
