Step 1. Compare all tied contenders based on their opponents' match-win percentages.
Step 2. Compare all tied contenders based on their game-win percentages.
Step 3. Compare all tied contenders based on their opponents' game-win percentages.

Players receiving byes are considered to have won the match and earn 3 match points.

Examples:
• Player A has a record of 6–2–0 (Wins–Losses–Draws). She has 18 match points (6*3, 2*0, 0*1).

• Player B’s tournament record is 4–2–2. He has 14 match points (4*3, 2*0, 2*1).

Match-win percentage
A player's match-win percentage is that player's accumulated match points divided by 3 times the number of rounds in which he or she competed, or 0.33, whichever is greater. (Establishing a minimum match-win percentage [0.33] limits the effect low performances have when calculating and comparing opponents' match-win percentages in Step 1 of the tiebreakers.)

Examples:
• Player C's tournament record is 5–2–1. She has 16 match points and she played eight rounds. Her match-win percentage is 16/(8*3) = 16/24 = .667

• Player D goes 1–3–0 in four rounds and withdraws. He has 3 match points and his match-win percentage is 3/(4*3) = 3/12 = .25. However, since Player D's match-win percentage is below 0.33, player D's match-win percentage is 0.33 instead of 0.25.

• Player E's match record of 3-2-0 includes a first-round bye. She has 9 match points (including 3 match points from the bye) and her match-win percentage is 9/(5*3) = 9/15 = .60.

Opponents' match-win percentage
A player's opponents' match-win percentage is the average match-win percentage of each opponent that player faced (ignoring those rounds for which the player received a bye). Use the match-win percentage definition listed above when calculating each individual opponent's match-win percentage.

Examples:
• Player F's record in an eight-round tournament is 6–2–0. Her opponents' match records were: 4–4–0, 7–1–0, 1–3–1, 3–3–1, 6–2–0, 5–2–1, 4–3–1, and 6–1–1, so her opponents' match-win percentage is:
(12/24 + 21/24 + 4/15 + 10/21 + 18/24 + 16/24 + 13/24 + 19/24)/8 opponents.

This translates to:
(0.50 + 0.88 + 0.33 < raised from 0.27> + 0.48 + 0.75 + 0.67 + 0.54 + 0.79)/8

With the individual match-win percentages added together, this equation becomes:
4.94/8

Player F's opponents' match-win percentage is 0.62.

• Player G's record at the same tournament was 6–2–0. His opponents' records were: bye, 7–1–0, 1–3–1, 3–3–1, 6–2–0, 5–2–1, 4–3–1, and 6–1–1, so his opponents' match-win percentage is:
(0.88 + 0.33<raised from 0.27> +0.48+0.75+0.67+0.54+0.79)/7 opponents

With the individual match-win percentages added together, this equation becomes:
4.44/7

Player G's opponents' match-win percentage is 0.63.

Game points
Game points are similar to match points in that players earn 3 game points for each game they win and 1 point for each game that ends in a draw. Unfinished games are considered draws. Unplayed games are worth no points.

Examples:
• Player E wins a match 2–0–0, so she earns 6 game points and her opponent receives 0 game points from the match.

• Player F wins a match 2–1–0, so she earns 6 game points and her opponent earns 3 game points from the match.

• Player G wins a match 2–0–1, so he earns 7 game points and his opponent earns 1 game point from the match.

Game-win percentage
Similar to the match-win percentage, a player's game-win percentage is the total number of game points he or she earned divided by 3 times the number of games played.

Examples:
• Player H plays in a four-round Swiss-style tournament. His game record is (by match):
2 wins (6 game points)
2 wins and 1 loss (6 game points)
1 win and 2 losses (3 game points)
2 wins (6 game points)

Player H has 21 game points and his game-win percentage is:
21/(10*3) = .70

• In the same tournament, player I's game record is (by match):
1 win and 2 losses (3 game points)
1 win and 2 losses (3 game points)
2 losses (0 game points)
1 win and 2 losses (3 game points)

Player I has 9 game points and her game-win percentage is:
9/(11*3) = .27

Opponents' game-win percentage
Similar to opponents' match-win percentage, a player's opponents' game-win percentage is simply the average game-win percentage of all of that player's opponents. And, as with opponents' match-win percentage, each opponent has a minimum game-win percentage of 0.33.

Byes
When a player is assigned a bye for a round, he or she is considered to have won the match 2–0. Thus, that player earns 3 match points and 6 game points. A player's byes are ignored when computing his or her opponents' match-win percentage and opponents' game-win percentage.
