It appears that the size of the hash table has a big impact on Kn/s in the case
of Fritz 8.  What about Crafty v18.11?  What hash table size is used to obtain
the data for the Crafty v18.11 Benchmark testing?

We already talked about the impact of the choice of position.  The way that
problem is addressed in the test was explained by Bob Hyatt.  But no information
yet on the hash table size used in that test.  Are several different hash table
sizes used and then an average Kn/s calculated?
