I have seen it written here that with 64 bit Zobrist hashing, the perfect key should change 32 bits. When I had what I thought to be hashing problems, I captured some stats on my hash keys. I found that most of them changed 28-36 bits (within 4) with a few outliers as far as 13 bits from "perfection". I also checked that I was not generating duplicate keys. How good or bad is this? Should I work on the average, or the outliers? Any comments appreciated :) Pat
