I’d just like to amend (title) tournament tiebreakers, because the current system is not entirely logical.
The title tournament results (including the decision of title match participants and trophy assignments) would use the following tie breaker (which has been implicitly applied for a while):
- Points (High > Low)
- Status (Normal > Disqualified > Resigned, disqualifications due to system hiccups would be treated as Normal)
- SOS (High > Low)
- SODOS (High > Low)
- Overall Rating
Obviously no disqualified/resigned player should win, but if there is a reliable way to distinguish proper DQ from ‘server hiccup DQ’, I’m fine with 1>2.
SOS. Alright, if you have the same number of wins as someone else, ‘having played ostensibly stronger opponents’ should be valued higher. Now the trouble with SOS is DQs/Resignations. Maybe A’s opponents were stronger than B’s, but more of them quit the tournament. In this case it becomes confounded with ‘having played fewer quitters’. I don’t have much of a problem yet with this one though, mainly because I haven’t looked at how bad this problem is. Perhaps we could change this to “Sum of Opponents’ Status”, 0 for DQ/res and 1 for active. Bonus: the abbreviation would stay the same.
SODOS. And here I clearly disagree. It should be head-to-head. Why? Well if you’re even on points and your opponents were ostensibly equally proficient, if A has a winning record against B, it’s hard to argue that the player with a losing record should outrank the other. Finally, to quote Christoph Gerlach (who wrote his dissertation on McMahon pairing):
Using SODOS as a tie breaker after SOS is also questionable. If SODOS will discriminate between two players, these two players have the same SOS. Let’s say Player 1 has a higher SODOS, this means that he has won to stronger opponents compared with Player 2. But he also lost to weaker opponents compared with Player 2 (we know this because both have the same SOS). Would anyone really think it is more significant to win against stronger opponents than losing to weaker opponents?
- Overall rating. What? This makes absolutely no sense and should be replaced by a Tie-breaker game. Yep. If you’re tied on score with someone and your opponents have fared equally well and you drew in the head-to-head, the only logical tiebreaker is one more game.
