X = BR ( 1 + sqrt(1 + 4 I N 0/(k BR)) ) / 2
This is a formula from (http://www.bj21.com/bj_reference/pag...lformula.shtml) for when you have a bankroll you are playing with , but you have a regular-job that allows you to put savings into the BankRoll .
X is a number that you can use for a imaginary BankRoll , because of the constant adding to BankRoll , this is what, in theory , we can use to size Max bets with . I need to solve for X , I did this fast , and am tired , I would very much like better math people than me to look at my work below, for errors and please comment , thank you
Variables legend :
BR this is the part of my Bank Roll I'm willing to put up as risk, for this formula I just used $ 2,000
I is the non-gambling income per round (or the
non-gambling income per month divided by the number of
rounds you play per month), in reality I make a different amount each month , for this formula I just used $2,000 and for hands per hour I used a very small number because of ploppies being slow sometimes and wonging alot to slow things down , so I just used 50 hands per hour or something like that , I wong in and out alot , trying to cut down.
and sqrt() is the "square root" function.
N 0 is the doubling time in rounds, --- I use a style very similar to COB , just with 5-50 spread, 6 deck games ,
k is your Kelly factor ( I used 0.75 ),
X is now going to be , the effective bankroll that you are allowed to use to size
your bets,
( I set it up for 10 hours of playing time per month, that's about average for me , most others will use a much higher number there)
We do the work in the parenthesis first ...
X = 2000$ ( 1+ sqrt of ( 1 + 4* 4 * 10,000 / .75 * 2, 000) / 2
X = " " 1500 / 2
X = " " ( 1+ 160000 / 1500 ) / 2
X = " " ( 1+ 106.67) / 2
X = 2000$ ( 1 + sqrt of 107.67 ) / 2
X = 2000$ ( 1 + 10.3764) / 2
X = 2000$ ( 11.3764) / 2
X = 22752.8 / 2
X = $ 11376.40
