Craps: Any validity in precision shooting?

[skitzo444]

I have been reading about precision shooting and talking to an old friend who is a serious craps player (Full table in his basement) He says that by setting the dice and holding it a certain way you can change the probability of dice by going through a consistent motion.

In theory I can see how this would work but doesn't the deflection on the craps layout and walls randomize any attempt at setting the dice?
