BrainKing has a lot of running tournaments, so as El Cid said, it might take too many resources to run every hour - but to save a ton of programming, I think the idea that a user can "ask for next round to start" button where someone who knows how to see if the results could re affected by current games could then manually assign the winners from each section to start next round (and let remaining games that don't matter to the tournament to continue) - it might be a solution to help with the amount of programming to calculate if the results can be different.
