After 11.040 games, 24 engines included
ELO are fixed to 2.800 for Shredder 12 32bit. All other engines are derived from that fixed number.
Calculated with: Bayesian 0056
The separate columns give the (mean) Elo performance, the + and - margins of error given with 95 % confidence,
the number of finished games, the relative score given in percentages, the average opponent ELO and finally the
