Please note that the three lists are updated separately to each other.
Also please note the live link will no longer necessarily give you the most updated lists. The links given in each update report will be the ones to use.
The links to the various rating lists can be found just beneath the default Best Versions list.
For example there is a 32-bit Single CPU list.
Our 40 moves in 40 minutes repeating and 40 moves in 4 minutes repeating are both adjusted to the AMD64 X2 4600+ (2.4GHz).
Currently active testers are:
Graham Banks, Shaun Brewer, Aser Huerga, Kirill Kryukov, Dom Leste, Wassim Saeed, Andreas Schwartmann, Charles Smith and Gabor Szots.
Be aware that in the early stages of testing, an engine's rating can often fluctuate a lot.
It is strongly advised to look at the many other rating lists available in order to get a more accurate overall picture of an engine's rating relative to others.

Stats/Presentation Notes
The LOS (likelihood of superiority) stats to the right hand side of each rating list tell you the likelihood in percentage terms of each engine being superior to the engine directly below them.
All games are available for download by engine, by month or by ECO code not from the live link though).
ELO ratings are now saved in all game databases for those engines that have 200 games or more.
Clicking on an engine name will give details as to opponents played plus homepage links where applicable.
Custom lists of engines can be selected for comparison.
An openings report page lists the number of games played by ECO codes with draw percentage and White win percentage. Clicking on a column heading will sort the list by that column.
