That's not what I am seeing on the PIII 800, I too see it but don't beleive it.
In some endgames Hiarcs 7.32 is seeing over 200 Kn/s. I Ran LCT II and Compared
it to the shep site Results ran on a PIII 550. I was almost exactly 2x faster
then the times he had posted for the same positions. I have the time and results
if you want to look at them for each position.
