Quick question: What\'s the formula for calculating a weighted SD?

TIA -- greatly appreciate it. (I know it's in one of Mason's books, I just don't have it handy right now.)

(By weighted SD, of course, I mean to calculate specifically one's SD/100 hands when one has figures like a win rate of 20BB over 150 hands, then -15BB over 90 hands, etc. etc.)
