    go to articles and search for "rating" :) there is a good article on the topic of ratings and what glicko RD is.

    Ratings deviation. If you know statistics, it's like the standard deviation.

     

    Your rating is 1532 and your RD is 113. That means with 95% confidence your true strength is between 1306 (rating - 2 x RD) and 1758 (rating + 2 x RD).

     

    My rating is 1770 and my RD is 188. That means with 95% confidence my true strength is between 1394 (rating - 2 x RD) and 2146 (rating + 2 x RD).



    The more often you play, the lower you RD becomes.

    leggy, I think now only paying members can see their RD. Click on "My Home" (top right) | "Online Chess" (top right) | "See Full Stats Page" (bottom right).
