Tiebreakers:
1) Average of your opponents' Match Win Percents.
For each of your opponents, divide the number of rounds they've won by the number of rounds they've played. Sum those numbers and divide by the number of opponents. Each opponent who would contribute less than 25% this way instead contributes 25%. A bye is not included when doing this calculation. Round the result to its first two decimal places only, i.e. 34.56%.
2) Your Game Win Percent.
The number of games you've won divided by the number of games you've played. A bye is not included when doing this calculation. A draw does count as a game played but does not count as a game won, even partially, so games that result in a draw will reduce your GWP.
3) Head-to-head.
If two players have equal match records and 1st and 2nd tiebreakers, then if those players have been paired against one another in this event, the winner of that match is ranked higher.
