I suspect that the *real* NPS is higher.  What I mean by that is that a
tablebase hit is a giant hidden pile of "invisible" nodes.

For instance, if I take some endgame EPD positions and have crafty pound them
with no tablebase files at all, I will get a high NPS figure of about 200K.  If
I add tablebase files, it may go "down" to 180K.  But if you look at the depth
in plies searched, it will average a deeper search than before.  So the NPS goes
down but the *REAL* search speed goes up.

So much for NPS.
