Good example for the validity of the generally accepted 7% rule per
doubling of transposition table size which I mentioned earlier ...

Going from 12MB to 98MB is not a 4-fold but an *8-fold* increase
in size which is equivalent to 3x doubling. The 7% rule then predicts
a roughly 3x 7% = 21% better performance. Very close to your observed
23% for "Fritz5", isnt' it?
