Fixed TC = 148.5 – 91.5 = 61.87%
Incremental TC = 143.0 – 97.0 = 59.58%
Global Score= 291.5 – 178.5 = 60.73%
Against : Houdini 4.0 St. Ct0 (3227) = 53.44% ; Komodo TCECr (3181) = 66.87% , Gull 3 XP (3199) = 61.87%
Average Estimated Elo Opponents = 3202
Estimated Elo Performance= 3277 Error bars= +/- 23 EEP
This is the second best register ever in my tests. Only 4 Elo points below the top scorer. It seems that, under my testing conditions, the latest SF are consolidating around 45 Elo Points above Houdini 4.
