playBunny: good point about infinite vs. finite series, an important difference! I could roll the dice a million times and never roll a 7. But infinitely, I know the texts say one should get perfect distribution, but I have trouble intellectualizing that one, because i can't see a practical way to prove it.

I, too, would like to know EXACTLY what trips the payoff and % payout adjustors, does anyone know who's an insider?
