Hi all, Now that I am a little better from my health hiccup I wanted to try something a little bit different this season. Does anyone remembers the Coventry Telegragh article about the Sky Sports predictor, "Elo"? Coventry City's predicted promotion prospects Its basically an old chess rating system. Well, let's add some bells and whistles to it and update it a little. The home page of Glicko-2 can be found here. Mark Glickman's Home Page More technical stuff is in here. https://www.englishchess.org.uk/wp-content/uploads/2012/04/The_Glicko_system_for_beginners1.pdf Even more technical stuff. (PDF) A Comparison between Different Chess... I certainly don't understand this but it is what the main chess servers use to rate the players that frequent there. I've been having a late night look around the net and found a Glicko-2 calculator. The ratings deviations doesn't show up on the website so I would recommend waiting until past the twelfth game for the RD to drop from 350 to 50. This is where there is confidence in the rating that it is in close proximity to the playing strength of the side. This is all Public Domain stuff.
