I've never messed with dice setting. I suppose there might be something to it, but I also know I haven't got the time or energy to practice and develop the technique. (And by the time you divide you winnings by the time you needed to perfect it, you would find you are paying yourself a paltry salary indeed!)

Mostly, I regard dice setters as superstitious - especially since I have never noticed a benefit while actually at the table. I tend to reject superstition since it is unlucky to be superstitious.
