The real problem is that by round 6, the winner is pretty certain, although three games against weaker opponents are left, and there the luck factor often lurks behind a pawn and jumps out to present a surprise and knock one of the top players off. log2(#players) is a good number of rounds for starters. one more gives a couple of more top finishers a better final result. But too many and many of the final rounds are simply meaningless, as we've seen multiple times. For example, at the last WCCC they tried to fudge the round-robin pairing to put a few of the "interesting games" on the final few rounds. Didn't work out at all and the event was over early... There can always be too many rounds in a Swiss. 9 is on the edge. Both in final results and in total time required to play 9 games...
