Recently I initiated a discussion here about how to resolve a
three-way tie in a round robin event.  There were many good responses,
but there was not total agreement.  Since then, I made an inquiry of
the United States Badminton Association.  Below is the reply.

This is from the IBF rules and adopted by the USBA.

Round Robin - Procedure to solve a tie

The procedure to solve a round robin tie is as follows:

1.  Ranking will be established by the number of matches won.

2.  If two players / pairs have won the same number of matches, the
winner of the match between them will be ranked higher.

3.  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.

***  If this still leaves two players / pairs equal, the winner of the
match between them will be ranked higher.

4.  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.

5.  If this still leaves two players / pairs equal, the winner of the
match between them will be ranked higher.

6.  If three or more players / pairs are still equal, then ranking
will be established by drawing lots.
