I know it happened in 10 minutes per game but only after a very long game.
I think the reason it happened is that the program need a constant time to
start to use their hash tables.

I think it is a mistake in Fritz5.
The program should know that if it have not time to use big hash tables
it should  not waste time about starting to use big hash tables.
