I can't find this explained in the manual.
Obviously this is the standard deviation on the win rate, but more than this is not clear.
Firstly what are the units it is in? Looks like it's just in bb/hand, but I'm a bit suspicious from my numbers that it's actually in bb/100 hands (bb = big blinds) or it could even be big bets.
Secondly the standard deviation on win rate varies depending on sample size. You obviously calculate it by dividing the total number of hands into blocks containg y hands then calculate the average variance over the whole sample for a block of that size. What is y? I assume 100 hands? Or is it ten or even just 1 hand? Hope this is clear.
In case the above is not clear I am talking about sample variance (obv take the square root to get standard deviation) as described in e.g. http://mathworld.wolfram.com/Variance.html, which I assume is what HEM is calculating.
