Based upon 222 wrestling schools participating in 2016-17 school year you would have 36 in 6A, 36 in 5A which leaves 150 schools with wrestling then you take that times .40 and that gives you the 60 sixty schools for 4A. I am not for sure how many will have wrestling this year but you will subtract the 72 schools that would be in 6A and 5A then you take 40% out of that remaining number of schools for class 4A. Then rest of the schools would be 3A. At least this is how I understand everything.
