Standard Deviation Question...

[shermn27]

I feel like this should be simple and that I should know it, but apparently I don't. So here goes:

If my win-rate is 2.74 BB/100 and I play 375 hands in one hour and plan on playing for eight hours a day (2000 per day), my expected win rate is then 54.8 BB/8 hour period (day). What I can't figure out is my Standard Deviation over that same 8 hour period.

Here are the details. My SD is currently 14.5607 BB/100 and the same rules above apply. I play 375 hands in one hour for 8 hours a day (2000/day). What is my daily SD and how do I figure it out? Thanks in advance.

Edited.

Your standard deviation in n*100 hands is squareroot(n) times your standard deviation in 100 hands.
