It very awkward when you do not follow this guideline as the top place partipants _usually_ will place each other other in the round indicated below (based on the number of partipants). After that they start playing lower rank opponents and then you end up with the situaion that you have. For the life of me I am not sure why this is not follwowed more often, this concept is so simple but it seems like is not adhered to in many cases. In a single elimination tournament with 64 partipants where you have a decisive winner in each event, it will take 6 rounds to determine the sole champion. College basketball uses similiar concept in the NCAA tournament. Start with 64 teams and after 6 rounds, you have the winner - it's based on the same principle. # of participants rounds 6-8 3 9-16 4 17-32 5 33-64 6 65-128 7 Michael Byrne
