I suppose that, in a lot of cases, that's true. My programs have a simple
evaluation function and that give me a big nodes/second. But there are some
other fact to care about. The use of killer moves, for sample, can easly raise
your n/s, because, when the killer move is generated separetly from other
moves... and if you cut that node, no other moves were generated. Another thing
is the goodness of coding or the compiler optimizations.

Maybe you can infer what you said only if it is the same program, or program
strictly derived from the same program (as the various Crafty clones).
