USA Badminton Pool Play (Round Robin) Procedure
USA BADMINTON POOL PLAY (ROUND ROBIN) PROCEDURE:
(Last Updated On May 17, 2005)
The following procedures shall be used for USA Badminton pool play in Trials events:
1. POOLS
Each pool shall consist of 2-6 players/pairs. There shall only be one pool if there are fewer than seven players/pairs. If there are 7-12 players/pairs, there shall be two pools (pool A & pool B). If there are 13-24 players/pairs, there shall be four pools (pool A, pool B, pool C, & pool D). If there are more than 25 players/pairs, the USAB Court Officials Committee (COC) shall determine the pool play format. The distribution of players/pairs to each pool shall be as even as possible.
2. POOL FORMAT AND DRAW
Drawing of all players/pairs into pools shall be made using a double-blind draw (two draws will be made - one to determine the pool and another to determine the player), subject to #3 below.
Each player/pair shall play every other player/pair in their pool once. The order of play shall be determined by the USAB COC prior to the seeding and drawing of players / pairs into the pool(s). After the completion of pool-play the rank order of players / pairs in each pool shall be determined by Regulation 4 below.
3. SEEDS
The seeded players/pairs shall be determined by the published selection procedure of the trial event.
Seeds shall be placed as follows:
a) If there is only one pool, no players/pairs are seeded.
b) If there are 7 players/pairs, one seed shall be drawn into each of the two pools.
c) If there are 8-12 players/pairs there shall be two pools and four seeds. The top two seeds shall be drawn one into each pool and the remaining two seeds shall be drawn one into each pool.
d) If there are 13-15 players/pairs there shall be four pools and four seeds. One seed shall be drawn into each pool.
e) If there are 16 or more players/pairs there shall be four pools and eight seeds. The top four seeds shall be drawn one into each pool. The remaining four seeds shall be drawn one into each pool.
4. RANKING OF PLAYERS/TEAMS AFTER POOL MATCHES
The ranking of players/teams in a pool after all the matches between players/teams in that pool are completed shall be established as follows:
a) Ranking will be established by the number of matches won.
b) If two players/pairs have won the same number of matches, the winner of the matches between them will be ranked higher.
c) If three or more players/pairs have won the same number of matches, ranking will be established by the difference between total games won and total games lost, with greater difference ranked higher.
i) If this still leaves two players/pairs equal, the winner of the match between them will be ranked higher.
d) If three or more players/pairs have won the same number of matches and are equal in the difference between total games won and total games lost, ranking will be established by the difference between total points won and total points lost, with greater difference ranked higher.
i) If this still leaves two players/pairs equal, the winner of the match between them will be ranked higher.
ii) If three or more players/pairs are still equal, then ranking will be established by drawing lots.
e) If a player/pair does not play all their pool matches, all the results of that player/pair shall be deleted prior to determination of the pool ranking order.
5. ELIMINATION ROUND
Once pool-play has been completed and the final positions of the players/pairs in each group have been determined using Regulation 4 above, an elimination round to determine the final ranking order shall take place as follows. The elimination round draw shall be made by the USAB COC by a double-blind procedure prior to commencement of the pool-play phase.
a) If there is only one pool, the pool rank order is the final ranking order and there is no elimination round.
b) If there are two pools, the elimination round shall consist of the winner of pool A playing the runner-up of pool B and the winner of pool B playing the runner-up of pool A. The winning players/pairs of these two matches advance to play each other for first and second place, while the losing players/pairs advance to play each other for third and fourth place.
c) If there are four pools the elimination round shall consist of the top two players/pairs from each pool. The winner of the pool containing the top seed shall be in the top quarter of the elimination round draw and the winner of the pool containing the second seed shall be in the bottom quarter of the elimination round draw. The winners of the other two pools shall be drawn into the two remaining quarters of the elimination round draw. The runner-up players/pairs from each pool shall be drawn randomly by a double blind draw into the remaining positions of the elimination round draw such that the winner and runner-up players/pairs from each pool are in different halves of the elimination round draw.
d) If a player/pair finished in a high enough position in pool-play to compete in the elimination round but chooses not to do so, that player/pair shall not be replaced by any other player/pair in the elimination round.
6. OTHER USA BADMINTON POOL PLAY (NON-TRIAL) EVENTS
It is recommended that all USA Badminton pool play (non-trial) events adopt these Regulations. At a minimum, rankings of players/pairs in all USA Badminton pool play (round robin) events must be determined according to Regulation 4 above.
