Default Question that might be too vague to answer.

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).

The key missing statistic is your standard deviation of per 100 hands. Suppose it is 30 BB per 100 hands. Then over a week in which you play 9,000 hands, your expected winnings are 180 BB and your standard deviation is (90)^0.5*30 = 285 BB.

About two times out of three, your actual weekly results should be within one standard deviation of the mean, or -105 BB to +465 BB. About 95% of the time, the weekly results should be within two standard deviations, or -390 BB to +750 BB.

This is the way to do it, but usually SD is a good deal lower than this, more in the 15-18/100 range.

I don't know my SD unfortunately since I don't play on PT sites yet (While I think PT is important the games I'm playing were worth giving it up). An SD of 30bb seems very, very high... I would guess mine is in the 16-17 range for LHE. I'm playing mostly stud these days but I don't have enough info to guage my SD other than to say that currently I'm a luckbox.
