Instead of playing hundreds of games to check if the impression is correct it is faster to get into conclusion by finding if Fritz7 search less nodes with higher hash tables. If Fritz does not clear the hash tables between moves or if the time it takes it to clear it's hash tables is very small relative to the time that is used in the game then common sense says that they should not be a significant factor in the games.
