I can easily fake evaluation that gives only those values. I suppose that you
mean that the values should be true values. How do you propose to do that ? If I
have an eval that gives absolutely correct values 60% of the time (and the rest
wrong), do you expect my program to be weak or strong ? If I get 70% right, am I
necessarily stronger ?

The question is, given two evaluation functions, to decide which is more
accurate.

This is a good question. Your answer does not seem to lead anywhere.
