Stronger Rybka 4 settings - FRC list updated

[Ray]

Shaun tested a Rybka setting at standard chess blitz. That setting, Rybka 4 C13510 64-bit, currently shows some +23 ELO over default settings, here:

I decided to test this setting at FRC as well, and I got a similar result, slightly better in fact, +29 ELO above default, and also the draw rate drops from 25% to 17%:

What is particularly stunning, is that Rybka 4 C13510 64-bit is +138 ELO above Rybka 3 64-bit, what a massive improvement

I decided to run the FRC database through ELOSTAT as well. Our ratings lists use BayesELO

ELOSTAT has a slightly more conservative view of things:

Rybka 4 x64 to Rybka 4 C13510 64-bit improvement = +16 ELO (BayesELO says +29 ELO)

Otherwise ELOSTAT is similar
Rybka 3 x64 - to Rybka 4 x64 improvement = +116 ELO
Rybka 4 x64 to Rybka 4 C13510 64-bit improvement = +16 ELO
Rybka 3 x64 - to Rybka 4 C13510 64-bit improvement = +132 ELO

BayesELO (the official list says)
Rybka 3 x64 - to Rybka 4 x64 improvement = +109 ELO
Rybka 4 x64 to Rybka 4 C13510 64-bit improvement = +29 ELO
Rybka 3 x64 - to Rybka 4 C13510 64-bit improvement = +138 ELO
