Yet it is possible that Christophe is right also. Probably, he was talking about crafty with its own dedicated machine and pondering on. In such a circumstance, maybe crafty can pull a few more cycles. Try testing that setup too, and watch the graph to see if it stays redlined 100% of the time, of if it dips sometimes for the other engines.
