Default Re: On a 30,000 hand downswing.....

Nice post.
How much would these numbers change as the SD increases? (too lazy/tired to run all the maths right now) Or, what I'm really asking is what would these numbers be for me, at 42 SD and 8ptbb/100?

I'll try to find the point at which you should expect to break even.

SD = EV
42 * sqrt(n) = n * 8
5.25 = sqrt(n)
n = 27.56

So, you have a 16% chance of being negative after 2756 hands.

2SD = EV
84/8 = sqrt(n)
n = 110.25

You have a 2.3% chance of being negative after 11,025 hands.

3SD = EV
126/8 = sqrt(n)
n = 248.06

You are 740:1 against being negative after 24,806 hands.

Let's say you play 2500-3000 hands a week. One out of every six weeks, you'll be behind. In a month, you're about 40:1 against being behind. After you play 25,000 hands, you are very unlikely to be behind.
