Different values for StdDev (BB/100)

[HarrysBread]

Hello,

I've been playing a few cash game sessions and there is something on PT4 I just don't seem to understand.

When I go to $ > Results > By session, my StdDev(BB/100) shows 307.76 for 1952 hands (image 2) but when I go to $ > Results > By date, my StdDev(BB/100) shows 83.18 for the same number of hands. (image 1)

How should I interpret those values?

Thank you in advance :)

The summary row for this stat is the average of the rows in the table, so it's not the standard deviation of your total sample. The easiest way to find that out is to create a quick Player report on the My Reports page and add just that stat. Then you'll see your total standard deviation (which should be a bit smaller than the average standard deviation of your sessions).
