If a human being racks the balls, the possibility exists that there might be some gaps that a "pro" player (or really anyone with a bit of knowledge about the subject) may determine favors breaking from a particular location, speed, fullness of hit, etc. What is wrong with standing by patiently while the ref racks, then taking a few seconds to look over the result, not saying anything to anyone, making your determination how and where to break from, and then breaking the balls? The referees don't need to be pressured by the players...there ought to be enough pressure on them to perform the often difficult, if not damn near impossible task under some conditions, to rack the balls perfectly.
The only problem I can see with this is if the referee consistently gives poor quality racks, the player may feel they are being treated unfairly. Ignorance of the rack and the subtle differences, spaces, etc. is not a very good basis for determining the best way to handle this issue. The bottom line is that if humans rack, there WILL occasionally be spaces. Preventing the pros from knowing the conditions they are playing under (for example where the spaces are in the rack they have been served up), really takes pool farther from being a legitimate pro sport. Unless, of course, the knowledge about the rack could be wiped from the minds of all people forever. I don't see that happening. As such, some will have the knowledge, and will feel something wrong has been done if they are forced to break a a less than frozen rack. A big part of the problem is the voice of the people who either don't know or don't believe the significance of the spaces in the rack. "Just rack the balls and get on with it" really takes us a big step backwards. It is the exact equivalent of saying "Don't bother with that stuff that you know, because I don't know it and it doesn't matter to *me*"
Thoughts?
