Subject: Crafty's 32-bit pawn hash collision figures?

Hi

How many collisions crafty gets on average using 32-bit keys? So how many nodes
Crafty searchs on average to get 1 collision? I'm now using plain Visual C++ 6.0
rand() with no hamming distance tests and I get about 80 collisions out of
10'000'000 evaluations from initial position. I'd like to know if that is more
or less than Robert and David were seeing. Funny thing was that first I searched
about 5'000'000 nodes with no collisions, then I saw 40 collisions in a short
time, then again no collisions and finally 40 more in a short time.
