The data Y2 has presented suggests that small schools would be helped (not a huge difference, but I think other posters have highlighted some of the added benefits). However this represents about a third of the total student population, yet it seems to have a negative impact on the schools represented in the 2/3s majority. (can't read the implication of benefits in the #s without reading suggested detraction). All this suggests a negative impact total number of forfeits statewide.
It seems unlikely the IHSAA is going to act within the next few years even if there was consensus on the class issue. I think most agree that the class duals have been a good thing, and that had nothing to do with IHSAA. When they took away the state duals the coaches association stepped up and put together a great event.
Given its only the small schools that are at a disadvantage (I believe as a team and individual) in the one class environment. Why not create a small school state individual tourney? Run it in the weeks immediately following state as a 2 stage event with 4 regional sites at schools who would want to host finishing in an arena (Indy preferred). You could invite all teams in 1A & 2A and just use the 2 classes as is or even divide into 3 to accommodate the gaps at the high and low end. I know that entails a lot of work and funds, but I wanted to throw it out there.
