APPENDIX A—DCI RATING AND RANKING SYSTEMS

Elo Ratings System
The DCI produces Elo ratings for the all games it supports (see section 2 for a complete list of games)

The Elo player-rating system compares players’ match records against their opponents’ match records and determines the probability of the player winning the matchup. This probability factor determines how many points a players’ rating goes up or down based on the results of each match. When a player defeats an opponent with a higher rating, the player’s rating goes up more than if he or she defeated a player with a lower rating (since players should defeat opponents who have lower ratings). All new players start out with a base rating of 1600. The DCI uses the following equation to determine a player’s win probability in each match:

Personal Calculation:
1
Win Probability = --------------------------------------------------------------
10^(( Opponent’s Rating–Player’s Rating)/400) + 1

This probability is then used to recalculate each player’s rating after the match. In the equation below, players receive 1 point if they win the match, 0 if they lose, and 0.5 for a draw. Players’ new ratings are determined as follows:

Player’s New Rating = Player’s Old Rating + (K-Value * (Scoring Points–Player’s Win Probability))
