Z-SCORE – a statistic used to measure results more accurately with consideration of total matches played, and reflects the number of standard deviations from the mean performance.  The mean is assumed to be a 50/50 coin flip.

SDBG RANKING POINTS – Each match win is worth 1 point. For a standard sixteen person bracket, 1st place receives 12 points, 2nd place receives 8 points, and 3rd place receives 4 points. Splits of 1st/2nd each receive 10 points, and splits of 3rd each receive 2 points. For an eight person bracket, ranking points for 1st/2nd/3rd are halved. Forfeited matches and byes are not scored.

Elo – A rating system that measures the relative strength of a player. A player’s Elo rating increases when they win, and decreases when they lose. The amount of the increase/decrease depends on the strength of their opponent, how long the match is (e.g. 7 points or 5 points), and how many matches the player has played. The difference in Elo ratings between two players can estimate each player’s win chances in the match based on a formula. For example, a player whose rating is 100 points greater than their opponent’s is expected to win a 7 point match 58% of the time. Every player starts with a rating of 1500.
