I don't play BJ anymore. But I played mostly double deck. Occasionally I'd do some back-counting on the strip....but that's hardly worth it, when you include parking, walking in, etc. and on top of it all, it's still more work for less EV.

Not sure what you mean by win rate for multiple hours. EV is linear/additive, so you just multiply 1 hour of EV times the number of hours you're gonna play, and voila! If you're talking about variance, then the Std. Dev. is going to be:

((1_hour_SD^2) * hours)^0.5


This is, of course, how N0 is calculated, since EV outpaces SD the more hours you put in, while EV remains linear.


A real life example (with easy numbers, too) -- Say you have $100/hr in EV and 1_hour SD is $1k. That means after 10 years at 1,000 hours a year....


SD = (1,000,000 * 10,000)^0.5 = $100,000.
EV = 10,000 * $100 = $1,000,000.

EV +/- 1_SD = $900,000 to $1,100,000.
EV +/- 2_SD = $800,000 to $1,200,000.
