Maybe something then was wrong in your test or the data was too few.IWB wrote:I consider that a myth repeated to often.Laskos wrote:... I think the use of positive Contempt for rating lists would significantly increase Stockfish rating on these lists.
I played a full set of games against all opponents with SF 7 on the 18th of June 2016 and it (Version 7 at that time) gained 4 Elo with a Contempt of 20 (which was the prefered contempt in discussions at that date). 4 Elo is less than half one SD in my list, so basicaly it was noise and I might get the same with just repeating the normal SF games ...
You find the full information on my main page on that date (and on the 20th.06.16 the games of Komodo 10 without contempt).

Your stats from TOP16:
Code: Select all
Komodo 11.2.2 3315 : 3300 (+2053,=1144,-103), 79.5 %
Code: Select all
Stockfish 8 3299 : 3300 (+1918,=1310,-72), 78.0 %
This is a significant difference. Amplified by the fact that Stockfish 8 is second rated, and lower you go, lower that ratio should be.
Also, although in direct match Stockfish 8 beats Komodo 11.2.2:
Code: Select all
220 ( 37, 159, 24), 53.0%
