Just going off the numbers it appears very obvious that from a competitive standpoint, making Class 1 the catch-all (and not allowing private schools to play in the smallest classification) is best for everyone involved.
History shows us that if you play ball in Class 4 or lower and are in the bottom half of enrollment(unless you're a private school in Class 1), you have virtually no shot of winning a championship
Part (but certainly not all) of the reason for that is the enrollment differential. If you read right under the Class breaks I have included the enrollment differential with Class 1 as the catch-all and then under the current Class 5 catch-all.
Classes 1-4 see the biggest benefit, but you can look at the breakdown for yourself.
Another potential benefit, with Class 1 being considerably more competitive, some of the schools that have gone 8-man may decide to give Class 1 a go, and start refilling the lowest Classification.
