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, Ray Banks, Shaun Brewer, Kirill Kryukov, Dom Leste, Denis Mendoza, Wassim Saeed, Charles Smith, George Speight 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.
40/40 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.
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.
A future development (no set date yet) will be the optional inclusion of engine logos, flags and continent pictures beside each engine name in the rating lists.
An example of what this will look can be seen here in Kirill's special free engines project - KCEC site
The engine logo will function as a link to selection of all engines from the same family. The country flag will be a link to selection of all engines from the same country. The continent picture is a link to selection of all engines from the same continent.
This feature will be implemented once Kirill can find the time to do it.
