(very) simple math suggests 3A and 4A are fairest groupings.
As percent size of smallest school population to largest
5A 38%
4A 63%
3A 64%
2A 27%
1A 28%
Certainly no expertise here but seems pretty basic algorithm used to group by forced ranking and dividing pool into by 5.
Always going to have someone top and bottom of each range (with clear advantage/disadvantage) with that system.
