MadMonkey: Actually I meant a manual "before schedule" finish round, so that tournaments where no games (or just a few) have finished wouldn't saturate the system. Of course, if no one noticed a group had already been decided, it would be as it is now.
maybe it could be also considered/added that on single elimination tournament, a round could start game by game, so if games 3 and 4 had finished, the winners would start their next game without having to wait for all the games to end (I know this has problems with fisher clock, but those problems happen to at the moment
