Though, it might make more sense to run the group stages to:
Group stages4 groups of 4 = 16 players.
Everyone plays 2 sets versus each other (1 point per set won).
6 matches per group * 2 sets per match = 12 sets per group.
48 sets in total over group stage (4 groups of 12 sets).
Time: 192 minutes (48 sets * 4 mins per set).
Total time: 48 minutes for group stages (240 minutes divided by 4 tables)
That would make the total time:
48 + 10 + 10 + 20 = 88 minutes = 1 hour 28 minutes. (gives us more time in the event of delays, which are probably pretty likely?)....
Will make a final decision and post on a new thread (this one is way too long now!
) later today.
