RoR Curve

Hello there,

I recently read Ken Uston's Million Dollar Blackjack and I was doing calculations with the Element of Ruin given in the book.
There are example calculations for a RoR of 5% and there are three graphs for 3%, 5%, and 10%, where you could draw lines and figure out the certain bet for each Uston Advanced Point True Count.
However, does anybody know the equations for the graphs? (they go for +infinity for x->0 and for 0 for x->+infinity.)
It would be easier to calculate the bets if there is an equation for each of the graphs.

Example
Apparently the link does not work here?


Thank you

Also, how could on get a function from this table

x / f(x)

0.5 / 240
1 / 150
1.5 /110
2 / 75
2.5 / 65
3 / 55
3.5 / 45
4 / 38
4.5 / 35
5 / 32

SimonEggi,

Well, just eyeballing the numbers while lying in bed, I can see that f(x) = k/x, where k is about 155. Except for the first point, the fit looks pretty good.

Hope this helps!

Thank you, i figured the same but the first point threw me off. There probably is no more precise way to do this?

And what about the other two Graphs of the Link? Just moved by certain amounts into x and y direction?

SimonEggi,

I answered this question for you over on Norm's BJ the Forum board, because I got frustrated trying to upload an image: see
