Round Robin Schedule was supposed to be as follows:
DAY DATE BD # 1 BD # 2 BD # 3 BD # 4 BD # 5 BD # 6
Mon 23-May 10 @ 11 2 @ 9 6 @ 8 3 @ 7 1 @ 5 4 @ 12
Mon 6-Jun 3 @ 8 5 @ 11 4 @ 9 10 @ 12 6 @ 7 1 @ 2
Mon 13-Jun 5 @ 9 3 @ 12 1 @ 7 4 @ 8 2 @ 11 6 @ 10
Mon 20-Jun 4 @ 6 8 @ 12 2 @ 10 1 @ 11 3 @ 9 5 @ 7
Mon 27-Jun 1 @ 9 3 @ 10 7 @ 12 5 @ 6 2 @ 8 4 @ 11
Mon 11-Jul 2 @ 5 4 @ 7 3 @ 11 9 @ 10 6 @ 12 1 @ 8
Mon 18-Jul 7 @ 8 6 @ 11 4 @ 5 2 @ 3 1 @ 10 9 @ 12
Mon 25-Jul 2 @ 6 1 @ 4 8 @ 10 7 @ 9 4 @ 12 3 @ 5
Mon 1-Aug 1 @ 12 8 @ 9 3 @ 6 2 @ 4 5 @ 10 7 @ 11
Mon 8-Aug 1 @ 3 2 @ 7 5 @ 12 8 @ 11 10 @ 11 6 @ 9
Mon 15-Aug 2 @ 12 7 @ 10 9 @ 11 5 @ 8 3 @ 4 1 @ 6
However, week one Team 4 played 10 and 11 played 12. This was not noticed until this past week (July 18th)
The following matches still need to be played:
Mon 25-Jul 2 @ 6 1 @ 4 8 @ 10 7 @ 9 4 @ 12 3 @ 5 (Team 4 listed twice. Team 11 not listed)
Mon 1-Aug 1 @ 12 8 @ 9 3 @ 6 2 @ 4 5 @ 10 7 @ 11
Mon 8-Aug 1 @ 3 2 @ 7 5 @ 12 8 @ 11 10 @ 11 6 @ 9 (Team 11 listed twice. Team 4 not listed)
Mon 15-Aug 2 @ 12 7 @ 10 9 @ 11 5 @ 8 3 @ 4 1 @ 6
Is it possible without having someone double up and someone else not ever play for a week?
It is possible to fix your schedule by completely rescheduling the last 4 rounds.. For example you could play:
2 @ 6 1 @ 12 7 @ 10 9 @ 11 5 @ 8 3 @ 4
1 @ 4 7 @ 9 3 @ 6 5 @ 10 8 @ 11 2 @ 12
8 @ 10 2 @ 4 7 @ 11 1 @ 3 5 @ 12 6 @ 9
4 @ 12 3 @ 5 8 @ 9 2 @ 7 10 @ 11 1 @ 6
This is one of exactly 16 ways of solving the problem!
