At the BWC, we will have a bracket of 7 and another of 6. The top 6 teams will advance, meaning the top 3 from each bracket. Having 13 teams is a real pain, however I have made it a habit of following the PSP and APPA suggested ways of forming the brackets. This solution allow for us to use Head to Head tie breakers in the preliminary rounds, which is a much better tie breaker measurement than others that would be available if we did not bracket the odd number of teams.
We will take the top 6 teams at the Beltway Challenge. Seeds 1 and 2 will advance to the semi-finals. Seeds 6-3 will play a quarter-finals match. Winners will move on to semi-finals to play against seeds 1 and 2.
I hope this helps.
