Count of days lost/won is sometimes wrong in quit_while_youre_ahead.py

[chapmanjacobd]

I don't know the rules for roulette but the results don't seem right to me?

Simulating playing roulette over 100 days where you stop playing each day after winning 10000 or after losing 1000
Days where you came out ahead:  100
Days where you came out behind: 0
Total amount bet:               10000000
Total amount remaining:         9900000
Net winnings:                   -100000

The only thing I changed in the code is simulating 100 days instead of 1000. If I never had a day with a net negative amount, how can it be negative net winnings?

I believe it's counting days where you won/lost 0 as a win, see the <= here: https://github.com/pirate/experiments/blob/master/quit_while_youre_ahead.py#L64
