Yes, I agree with you completely as well as your last post.   The only
think I would point out is that we need to run the Crafty version at
the same level and use the same "matching" criteria.   What are we
considering a match?  I proposed 2 ply and beyond at one point, Bob
says he took 3 minutes to 10 minutes and one of the testers posted
results that says he calls it a match only if his program wants to
play the move at the end of the 1 minute.     What criteria did you
use?

You last post hits the nail on the head,  we compare match rates
against Crafty (under the same testing conditions) and compare.
But let's make sure we are using the same testing conditions.
