The Glicko System is a method of determining your skill when rated against the rest of the league. To see how your Glicko and RD would be affected by playing a certain player, enter the values below. Your Glicko Your RD Enemy Glicko Enemy RD Who Wins You Enemy Your New Glicko 0 Your New RD 0 The Glicko System was developed by Mark Glickman to rate game players when they play against another player of a known rating. This system takes into account the amount of time between games, the reliability of your Rating, and the rating of your opponent and his reliability. A detailed description can be found at Mark Glickman's Ratings page. Basically you want a high Glicko Rating, and a Low RD. Your Rating is color coded according to your RD. A high RD (Over 200) is listed in RED, meaning you have a high Deviation and your Rating isn't very accurate. A medium RD (between 100 and 200) is listed in YELLOW, and is a better Deviation, meaning that your rating is closer to the correct rating. A low RD (less than 100) is listed in GREEN, and means that your rating is fairly accurate.
