Bankroll and Standard Deviation

[Wayne Schu]

I am new Malmuth's 'Gambling Theory', have some questions and figured you guys were the best people to ask. I am a very serious student of the game, and I figured this book would be the best to teach me about how to manage my bankroll. I am not a very strong math student, but have a strong desire to be taught this information. If this info is in the book and I could not identify it, please excuse my ignorance. Any help would be seriously appreciated.

-Although there are many examples, I want to make absolutely sure I can find my standard deviation. Can some one possibly throw me yet another extremely simple example for sample gambler?

-Once I do find my SD, how do I know it is a good number? What should the average SD be for a 5-10 player... a 8-16, a 15-30? Is there a little formula that can be used to find that information?

I think I'll grasp the 'math' part pretty easily, but more importantly, are my numbers decent for a gambler? Thanks for any help.
