The shape of a 25-team bracket

25 teams in a 32-slot bracket leave 7 byes, for seeds 1 to 7. The other 18 teams play 9 round-1 games, from 16 v 17 down to 11 v 22. After round 1, 16 teams are left and the bracket is full from there.

If the favourites win

That puts seed 1 against seed 4 and seed 2 against seed 3 in the semifinals.

SeedOpponents if favourites win (game)
1bye, then 16 (G10), 8 (G18), 4 (G22), 2 (G24)
2bye, then 15 (G14), 7 (G20), 3 (G23), 1 (G24)
3bye, then 14 (G16), 6 (G21), 2 (G23)
4bye, then 13 (G12), 5 (G19), 1 (G22)

How many games each team plays

The fewest is 1, for a team that loses its first game, which for a bye team is its round-2 game. The most is 5, and 4 for a champion that had a bye. In the favourites-win run, seed 1 plays 4 and seed 25 plays 1.

How long it takes

24 games at 30 minutes is 12 h of court time. No round has more than 9 games, so extra courts beyond that sit idle.
