Re: Standard Deviation of PT Stats (Light Math)
[ QUOTE ]
Basically, you can be about 99% confident that your "true" winrate is within 3 standard deviations on either side of your current average winrate after 13K hands. I believe the confidence interval for just one SD is about 78% or so.

You're getting "standard deviation" confused with "standard error."
Chris had a thread a while back describing how to go from SD to SE and how to estimate the confidence interval of your winrate.
