That would fill up the hash table exactly, if it had a perfect even
distribution.  The earlier tests I did to get the best analysis database
size indicated that the best number of buckets is about 3 times the number
of items you're going to store in the hash table.

So by that count it should be 3/10th, which is about 1/3rd.  But again,
that's just for this particular test.  Theoretically it could be much
more.  Perhaps just using the analysis db size, without a multiplication
factor?  That should be plenty big.

Cheers,
Peter
