Modified double elimination. Undefeated team needs 3, team with one loss needs 5. My format is, if undefeated team makes it to 3, event is over. If one loss makes it to 5 , the one loss team now has to get to 7 while undefeated still needs to reach 3 for the win. My question is, is this a common format, is it deemed fair for the finals, if true double elimination is not an option. Thank you.
