As you said in your message on September 28 "All engines using their own books excluding, Crafty, Goliath using general.ctg". So you used Tiger.ctg for the Tiger and presumable Ruffian's own book. It's important to realize that although it doesn't affect the conlusion of the experiment. My point with the experiment was that Ruffian is doing amazingly well *in spite* of being handicapped by its opening book. By giving it a better opening book we can expect to see a jump in its performance.
