In your article "Computing Your Standard Deviation" (
http://www.twoplustwo.com/mmessay8.html) you write "A good rule of thumb is to have at least 30 observations (playing sessions) for the estimate to be reasonably accurate." Roughly speaking, about how many hands per session should there be for this to be a good rule of thumb?
You also write, "for most poker games of any size, a standard deviation of 83.11 is not realistic. Expect a much larger number." What are the units on this number?
It's often said that one needs 100K hands to have a reasonable estimate of one's winrate. I've often wondered how many hands one needs to have a reasonable estimate of one's standard deviation. Hence, my first question.
Also, I've often read that 15BB/100 is a reasonable standard deviation in small stakes holdem. Hence, my second question.
Thanks in advance for any clarification you (or others) can give me.
