So FWIW, here is what my initial evaluation of the playoff W% data is. I'm also doing 2001-2022, and I am not classifying open-boundary publics with the privates. I could check the numbers with that change next, but I think it'd only make the analysis further off than Antioch's
Overall Private v Public Record
879 - 471, for a 0.651 win percentage in advantage of the privates.
Each Class with Share of 50% win seasons for the publics (first column includes exact 0.500, second column excludes). And total win % for private schools. Especially on the small schools, this looks way off from what Antioch twitter posted.
Code:
1A - 16 14 0.423
2A - 8 6 0.617
3A - 10 9 0.570
4A - 5 4 0.631
5A - 2 1 0.793
6A - 5 2 0.709
7A - 6 2 0.676
8A - 5 2 0.684
One interesting aspect of this I think is still the "have" v "have-not" debate. There are about 180 public schools who have lost to, but not beaten a private. 20 of these have an overall winning playoff record. The other 160 have a cumulative playoff record of 0.271. They aren't really winning against
most teams, private or public (478-1014 against public schools and 0-274 against private schools - mostly in small samples). Simply put, there is a early round competitive balance that's generally unrelated to public v private. These schools probably make the playoffs less than half the time, and they're rarely a tough opponent for whoever they're playing.
Overall, including those schools, you have 377 of 524 public schools who are the "have nots", with an overall losing playoff record. Only a handful (about 20) would flip their overall postseason record to > 0.500 if they had never played a private school.
This imbalance dichotomy does exist on the private side, but at a different scale/percentage. Here, you have 29 of 61 schools with a losing playoff record, a little less than half. And obviously since a greater portion of their total games will be against publics, their public v overall record tracks closely.
But drilling down even further, you have 11 of the 61 privates driving an overwhelming amount of the success: Driscoll, Mt. Carmel, St. Rita, IC, JCA, Naz, Montini, Providence, SHG, Newman, and Loyola account for 435 of the 879 private verse public wins at a win% >70%. And they make up half of all private school wins (beating other privates at a >50% share as well).
(Edit/note. This is 61 who made the playoffs in that time span. Doesn't include those who made no PO appearance in 21 years, if any - though I really didn't catch any obvious missing from the list)
I could also add the next three best win % private schools in Marist, Boylan, and Marian Woodstock. At that point, the remaining private schools now compete at a 0.500 level against publics. So about 1/5 of the private schools are really where this discrepancy shows. One is closed down, 2 others have only been juggernauts for about half this time frame.
Only 8 other private schools after these 14
advanced past a quarterfinal (7 having won 1 title and 1 having won 2). Though it should be noted neither Marian or Marist has won a title in this timeframe, placing 2nd once and twice, respectively). In total 53 1st and 24 2nd place trophies from the top 14 and then 9 / 4 from the group of 8.
Now if I took the top 20% of publics the bottom half of that list wouldn't be nearly as impressive at the bottom, but I could probably build a really strong 20-30 public schools whose success would look a lot like the private school 14. In fact, I can create a list of 36 who rank in the top 50 (among public schools) in both total playoff wins and playoff win %. They account for 69 first place trophies and 58 second place trophies.
Your next tier of Public schools (20 next best combined total wins and W%) account for another 10 and 24 1st/2nd trophies.
Now with ALL of this, of course, the trophies are split amongst classes because we first assign a classification and then the cream rises to the top. I wouldn't suggest that St. Theresa be elevated into a have group with Loyola anymore than I would suggest Forreston and Lincoln Way East be grouped. Whatever happens you're going to have a situation where the best see a disproportionate share of the success. Even if you can "solve" the "private school problem", the displacement created and new opportunity is just
so little, because the private school share of the population is so little. High school football, like the world, is very top heavy with the haves.

I'll pick on Antioch Twitter guys specifically a little here as well. In years where they made it past the first round:
04-05: +21 margin against public , -29 margin against public
08-09: +62, +1, +1 (publics) and -24 (public) in Semis
16-17: +1 (public) and -33 (public)
18-19: +49 and +1 (publics) and -7 (private) in quarters
19-20: +57 (public) and -7 (public)
Their other 2 losses against privates in Rd 1 (17-18 and 22-23) were by 22 and 21. Granted with some small, imperfect sample sizes, but... it doesn't look like the private schools are a competitive problem anymore than other publics are. Sure the draws can be super unlucky and random... but everyone deals with that. I'm sure its salty being eliminated early when you probably weren't a bottom 16 team in your class... but that's the imperfect seeding IHSA has.
