Make an option for a loser's bracket that is not strictly double-elimination
Our conference uses a bracket that has a loser's side. 8 teams play their first match, and if you lose that first match, you can not ever get above 5th place. So if you lose your first game and win the next two, you get fifth place. If you lose your first two games, you're done. The loser's side plays out just like the winner's side, but the winner's side and loser's side never play each other.
