Would still like to understand how the system decides who to schedule next in an unclocked tournament. As mentioned previously, I have not seen any repeats when we have 4 tables, and there are times when people have to wait 15 minutes. For example 3 rounds in, the 4 pairs A,B,C,D have all played each other and E,F,G,H are still playing, the system will always wait (no matter how long) for one of E,F,G or H to finish rather than have A,B,C, or D repeat. This is good, as we would rather wait and avoid playing the same pair twice. The problem is that the above logic does not seem to hold with 5 or more tables.
