Question that might be too vague to answer.

[Alex/Mugaaz]

I've come to the conclusion that I simply don't appreciate what kinds of swings should take place. Assuming someone is a 2bb/100 winner, plays 300hands/hr, and averages 30h/week. How could I make/find a graph that would show what kind of swings are normal over weeks/months. I really don't understand how good or how bad I'm running since I have nothing I can compare it too (actually I feel I'm running too good, so this isn't cliche whine post don't worry).
