I picked this format to avoid 2 problems:
- Swiss pairings invite collusion on the margin, if someone out of contention is paired up
- Double (or Triple) Elimination brackets have a multi-round delay at the end for the undefeated person while they wait for the losers bracket to finish. As well as smaller delays in the later rounds while the recent winners wait for the losers bracket to catch up.
2a. Traditional Double Elimination also makes wins in the winners bracket “worth more” - the two finalists in even a 16 person bracket will have records of 4-0 and somewhere between 4-1 and 5-1 depending on when the other player lost, and the spread gets worse as the tournament size increases.
