Hurst,
Not that I wouldn't call it, but...
My experience was that if you call it, and are vocal about "no more", the foul stops occuring.
For instance, if the first 3 times a player hits a player from behind on a ball in the air you call it and tell them no more in front of everyone, it usually stops. Therefore not needed to call it later, relaxing.
Consistancy is the most important thing. I am okay with a consistantly bad ref if they call it the same way all the time.
