Brett Harris originated the concept of N0. From his excellent article entitled The Theory of Optimal Betting Spreads, Brett tells us that N0 is "equal to the number of rounds that must be played, with a fixed betting spread, such that the accumulated expectation equals the accumulated standard deviation. As such, it is a measure of how many rounds must be played to overcome a negative fluctuation of one standard deviation with such a fixed spread." MathProf mentions that 4 * N0 hands must be played to overcome a negative fluctuation of two standard deviations and therefore 9 * N0 must be played to overcome a negative fluctuation of three standard deviations with such a fixed spread.

Enter the Standard Deviation:
[i.e. SD/100 from "Blackjack Attack"]
