Does the west really have more 3-2-1a schools?

Weren't the regionals basically split along a line that cuts from Belleville to Wichita with the schools east of that line going east for the NE and SE Regionals and the schools west of that line going west (with the exception of Garden Plain & Hesston) for the P-burg and Lakin Regionals?

And didn't each of these regionals have 14 - 16 teams (although the Lakin regional had a lot of partial teams)?

If this is the case, the count would seem to be pretty equally distributed among each half of the state.
