The answer can be found in the proposal from the committee that studied the classifications. According to Mark Lenz, the study is what wrestling will follow, which is not what was voted on by KSHSAA schools. 36 schools in 6A, 36 schools in 5A, and 60 in 4A. The rest 321A. It is my understanding that KWCA suggested 48 schools rather than 60 for 4A but somehow 60 is what stuck.
