quick easy question about SD and BR

[gp?]

yes, i've looked in the FAQ.

let me try again:

i'm trying to put together a BR for playing. i know my standard deviation is lower than average, so I think it is possible for me to start with a BR lower than average. i was wondering if there was any math that could be done where i could find exactly what i need.(similiar to how they calculate BR requirements given a SD in limit holdem)
