thx, Whats the variance? Like $2000?

[gay math not suitable for BBV]

standard deviation of blackjack = 1.2 (standard blackjack is 1.155, I'm assuming the SD is slightly higher because of the 2:1 BJ payoff)

SD 600 hands = 1.2*sqrt(600) = 29.4 units

Expectation = +10.3 units

So

65% chance of finishing between -19.1 units and +39.7
95% chance of finishing between -48.5 and +69.1
99.7% chance of finishing between -77.9 and +98.5

I guess that, if you do it all 3 days:

SD(1800 hands) = 1.2*[sqrt(1800)] = 50.91

expectation = 10.3*3 = 30.9

65% chance of being between -20 and 81.8 units
95% chance of being between -70.9 and 132.7 units
99.7% chance of being between -121.8 and 183.6
