Subject: Rating Lists

In another message I noticed how many useful and reliable rating lists we have
now. CEGT surely has been a big hit, expecially because SSDF, while as usual
outstanding, has been updating a little bit less lately. Then there is Kurt
Utzinger which has decided to run EloStat on his test, which were already highly
regarded. Then we have WBEC, CSS and a lot of others.

However, I noticed that good rating list (lots of games and fixed format) tend
to give pretty much the same results, as it is supposed to be. In the image
there is a comparison of Kurt's and CEGT lists (shifted to have the same
average) for the common engines. It is notable how almost all the engines have
perfectly compatible results, with the only slight exception of Gandalf 6.0.

The link to the image is http://host.ekono.net/images/files/2555/Chart.jpg

As soon as the new SSDF and WBEC lists are released I plan to make a comparison
of all the four lists.
