Thanks for the clarification, I was wondering about how to meassure this only a
few days ago.

Do you remember a position with very low firstmove_cutoff rates ? What was the
lowest percentage you observed in recent crafty versions ? Did you ever test the
distribution of fh on all possible moves , not only the first ?
