We are aiming for pools of 5 - 6 teams with games to 21 and a cap at 25. Based on the number of registrants this is not always possible. In cases where we need to make pools of 7 or 8, games will be played 15 with a cap at 21. If there is a mix between pool sizes within a division (ie there's a pool of 6 and a pool of 7) games will be played to 15 with a cap at 21. See example. As always tournament directors will have discretion to determine what they think will make for the best experience given the circumstances.
