I completely agree with you on this point, Amir.

"Hitech Hong Kong '95" searched around 150K nps and reached
iteration depths of 8-9 plies in the middlegame.

On of the main problems with its hardware was that it did
*not* support futility pruning which made it lose at least
one ply in overall iteration depth.
