...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
