Poker Tracker, Standard Deviation in session tab

does my SD/100 stat refer to one or 2 standard deviations?

For example: my SD/100 is 13. This means if it's 2SDs there's a 95% probability of my 100 hands netting me anywhere between -13 and +13 BB.

if it's only 1 SD, then there's a 66% prob of the same, and a 95% prob of me winning -26 to +26 BB in the same 100 hands.

If it's the latter, then i guess you need a sample of ~200k hands before it's at all reliable, right?

I'm asking on behalf of my noob brother, who is studying his SD.

Regards,

That is your 1 SD range.

I think 202.5k is the number I recall for good accuracy with a SD of 15 and BB/100 of 2/100.

Before the statistic it gives for SD is reliable? No, that will be accurate much sooner than 200k hands. SD converges much, much faster than win rate.
