I have here an unexplained phenomena:
1: In a duell between OliThink 5.11.4b and Minic 2.16, OliThink is about 31 ELO stronger.
Code: Select all
# PLAYER : RATING ERROR POINTS PLAYED (%) W D L D(%) CFS(%)
1 OliThink 5.11.4b : 0 ---- 5443.5 10000 54.4 4324 2239 3437 22.4 100
2 Minic 2.16 : -31 6 4556.5 10000 45.6 3437 2239 4324 22.4 ---
White advantage = 31.78 +/- 3.21
Draw rate (equal opponents) = 22.62 % +/- 0.45
2. In a gauntlet tournament it's only 1 ELO stronger:
Code: Select all

Draw rate (equal opponents) = 22.66 % +/- 0.22
White advantage = 31.78 +/- 3.21
Draw rate (equal opponents) = 22.62 % +/- 0.45
Who has an explanation for this?
