I disagree. Hiarcs is better in blitz and I expect result of 60% for Fritz6 in tournament time control based on the ssdf rating. I discovered that hiarcs suffers from a learning bug at tournament time control(there are cases when it needs more time to see something or cannot see something because it does not get the right information from the hash tables) and I guess that it is the main reason that hiarcs is worse at tournament time control.
