...after 160 games. I added the result of Shredder - Century 13.5 - 6.5
(+11,=5,-4).
Here is the new Elo rating list (the old values are given in parentheses).
Again Elo calculation was performed by iteration procedure (start Elo 2600).


    Program                Elo  (old)    +   -   Games   Score    Av.Op.  Draws

  1 Junior 6.0           : 2676 (2665)  101  74    40    60.00 %   2604   45.0 %
  2 Fritz 6a             : 2645 (2641)   96  86    40    63.75 %   2546   37.5 %
  3 Hiarcs 7.32          : 2624 (2615)  111  75    40    52.55 %   2606   40.0 %
  4 Shredder 4           : 2610 (2597)   90  66    60    51.67 %   2597   33.3 %
  5 Rebel-Tiger 12.0e    : 2603 (2598)  106  59    40    56.25 %   2558   57.5 %
  6 Nimzo 7.32           : 2599 (2592)   76 102    40    41.25 %   2660   42.5 %
  7 Century              : 2493 (2493)   73  73    60    32.50 %   2619   38.3 %


It is interesting to see that Century's rating did not change. Its Av.Op. is
also still the same. Therefore the result against Shredder fits very well with
Century's results before. Shredder increased its rating by 13 points up to 2610.
Due to the interdependencies of the iteration procedure the ratings of Shredders
opponents are also higher than before. And the ratings of the opponents of
Shredders opponents also increased. Hope I am not confusing you too much but
that's the way it works. You can simply check that the weighted average of all
ratings (weighted by the number of games) is still the same than it was before,
namely 2600.
So no significant changes after this match. Looking for the next one...

Bye
Frank
