Subject: and another Hash Table question...

Hello

the "hit ratio" of hash tables confuses me a bit. What is a hit?

I tried the LCTCMB01 position and got

1) 1.520.234 nodes
2)   263.041 entries in Hash table used
3) 1.458.957 probes in Hash table
4)   137.961 entries found
5)    40.777 entries have a "allright" depth to use
6)    37.517 match alpha, beta (upper and lower fails) and are used!

so i get a effective hit ratio of 37.517/1.458.957 =2,6%  ????

where do the 10% going around come from???

can anybody explain, how he counts and what numbers he get?

Greetings

Werner
