Information:

Last included: Edition 11! (last update: 14/01/2006)
The ratinglist is calculated by hand using the Ortwin Paetzold (IECG) method again because the EloStat list seems not to very good when different tournaments are included!
Only the lower ranked engines, below 1950 have an estimated rating calculated with BayesianElo because the difference in strenght in this group is too big to calculate the rating by hand.

    The version numbers are from the version which have completed the last tournament/Division where the engine have played in. - The calulation system is almost the same as the one used for the IECG ratinglists, for more information please look at the IECG rating example and/or IECG rating rules. The 4RR tournaments are calculated as 4 different 1 RR tournaments where the subrounds *.1, *.2, *.3 and *.4 are the different tournaments, the start rating for *.2 is the calculated rating after *.1 and so on.
