Ok, so pretty soon I'll start keeping a much conservative BRM of 100 Buy Ins. I currently have a 25 BI rule. I play 4 tables at a time of NL SH.
Ok, so when I keep 100 BIs I'll have a lot of capital on Pokerstars lying idle which I won't be using. I am thinking of withdrawing most of it and investing it in money market debt funds so that I keep earning a decent amount of interest on it. I'll treat that as part of my bankroll and as soon as I need it to play poker I'll redeem part of the funds and deposit them on stars.
Now comes the question of how much to keep in my stars account and how much can I withdraw. Here are some stats I have
bb/100 6.17
Std. Dev bb/100 69.5
Hands 105,900
I think its safe to assume that the sample is normally distributed (please correct me if I'm wrong).
So my interpretation is that there is a 68% probability that after 100 hands I'll be 75.67 bb up or 63.33 bb down and 95% probability that I'll be 145.27 bb up and 132.83 bb down.
So if I take the confidence level of 95% my confidence interval is (-132.83bb<x<145.27bb). Please correct me if you feel I was wrong in any of my assumptions and if I made any calculations mistakes.
I play a max of 2000 hands a day. How should I interpret this data and determine how many bb should I have in my account and how much can I invest so that my poker runs smoothly.
