Incremental TC = 150.5 – 89.5= 62.71%

Against : Houdini 4.0 St. Ct0 (3227)= 62.81%; Komodo TCECr (3181) = 63.44% ; Gull 3.0 XP (3199)= 61.25%
Average Estimated Elo Opponents = 3202
Estimated Elo Performance= 3289 Error bars= +/- 23 EEP
THIS IS THE NEW BEST SCORE EVER IN MY TESTS, 8 EEP above the previous leader SF Ipman’s 270414.
Please note that according to my tests,
something substantial has happened with Stockfish in the last four weeks, from SF 210414 -Bench: 7384368 Timestamp: 1398083427- to SF 170514 Bench: 8732553 Timestamp: 1400360347.
Both the SF Development and the fast RW and Ipman’s compiles have improved on average around 25 EEP in this short period of time. Amazing!!.
My congratulations again to the SF Team for this impressive performance. And to the compilers of RW and Ipman's for providing this useful benchmark that allows to evaluate SF progression with a narrow margin of error.

Tom Casanovas
