I created a tool you can use to see how much you'll have. The default is for Dec 31, 2010. You can also see how much you'll have in x number of days, or set a $ goal.
It's set for earning 10 BBs per day, and moving up once you reach 100 BBs of the next level. Just enter your current bankroll, and then click the maximum limit you expect to reach below. The default is LHE 10/20, since action starts to dry up there. There's a few bugs, since I only made this tool for my personal use.
