Posted before and sound like an old man but:
When I was a sophomore or junior in HS (early 90s) we were 7-3 or 8-2 but lost two division games and finished third, left out of the playoffs of a 8 team division. It hurt but we knew we had to play each week. Taking the top 4 if there are 7 or 8 teams in a region/district is fine. However, as we added 6A and now 7A, plus the consolidation of many small schools, there just aren't as many member schools playing so many districts have 5 or 6 teams with 1A football having 4 team divisions by default with the non football schools taking part in basketball.
If this remains the case the association should either only take the top 2 or at most 3 with division champs getting a first round bye. However, it would cut into "playoff" revenue. Of course 7A was to "increase excitement" which basically means to extract as much money as possible from the public and that includes school systems.
