Crafty actually calculates this.  It pops out at the end of a search.  The
"evals" number is the number of evals that run through the complete eval code
without taking a lazy exit...

I continually adjust the "max positional score" cutoff since the static
evaluation can produce some _really_ large numbers when transitioning to the
endgame...
