How sites are chosen. Each half’s 16 regionals are placed to keep total driving miles for all 32 teams as low as possible. A host school that wins its sectional plays at home. When the closest site would leave a team driving more than about 70 miles, a slightly longer site that shortens that trip can win, as long as it doesn’t hand another team a similar drive. Run against the IHSAA’s actual assignments, this method matched 30 of 32 sites in 2025 and 18 of 32 in 2024 (48 of 64). This is a projection; the IHSAA announces the real assignments after the sectional finals.

Sectional champions. When a team earns its Sectional badge, it is locked in as that sectional’s champion: its pick can’t be changed, autofill skips it, and Site Odds uses the actual result.

Confidence. Host: a host school plays at home. Strong: the next-best site costs 30+ more total miles. Likely: 10 to 30 miles. Toss-up: under 10 miles, shown with the alternate site.

Site Odds. For each team, the rest of its half is drawn 60 times, with each sectional’s winner drawn by its odds from the official IHSAA bracket and the ratings of record (finished matches locked in), and the site engine runs on every draw with that team as its sectional champion. Each draw’s projected site is not counted as a sure thing: it gets the share its confidence label has earned against the IHSAA’s real assignments in 2024 and 2025 (Host 100%, Strong 82%, Likely 69%, Toss-up 60%), and the rest is spread over the other hosts, most to the ones that add the fewest extra miles. Those rates come from 64 matchups, so read them as rough. Eliminated teams are listed as Out.

Distances. Driving miles from each school to each host site, from OpenStreetMap road data. They can differ from Google Maps by a few miles on rural routes.
