At the moment, Pebbles is creating a huge drift. Brian - CGOS requires us to use new names on the server each time we change our bots. It computes the strength using all games (heavilly biased with the results of the first 100 games) Pebbles is probably closer to 2000 ELO than 1000 ELO

The best way to get an accurate picture is to ignore the main page and go to the Latest Bayeselo which does a full performance rating on all games every played on CGOS. There will be no bias and you have error bars. The main page just tracks ratings incrementally and is not a very good

The Bayeselo page would not deal well with it, since it assumes each player is a unique individual with a fixed playing strength. In this case, the incrementally rated main page would do a better job. What I'm thinking about doing is to measure the ratings of active players compared to the

I recall reading about an Elo system that had better adaptation to players whose rating changes. It was called Glicko-2. Here is a link: http://en.wikipedia.org/wiki/Glicko_rating_system This would be a very poor rating system for CGOS. He basically recommends giving much higher K factors
