The first such experiment was run on horribly slow hardware years ago. Then Ken Thompson did the same with his belle machine and got the same results although at least 100X faster hardware was used. Hitech did the same thing for longer time controls. All three agreed. Monty Newborn and Ernst both investigated searching way deeper which simulates faster hardware than anything other than Deep Blue has, and they _both_ found that deeper is still better... with no 'tapering off' at least thru ply 15 in the middlegame. I'm convinced that faster = better, and that it is still linear and not getting worse.
