Two Plus Two Older Archives - Variability sucks!!

I thought about posting this in the general or theory section, but after seeing the current content...I decided here would be best!

I was reviewing my stats for my play so far this year and I have had a very successful year... however, I am a little concerned that my standard deviation is a little high. I am curious about things that you all may do... to lessen your variability?

My current stats are: (PS I only play live poker!)

Hrly Rate: 41.81
Total Hours: 823.5
Std Dev: 1405.75
--I typically play 15/30 or 20/40

I know this is not a completely large sample... however, my std dev this year is even larger then it was last year. My std dev for the last 2 years has been in the neighborhood of 20-25 times my earn, but this year it is nearly 34 times my earn. I also remember hearing that somewhere from 10-20 times your earn is a good std dev? Is that correct?

Please don't flame me... I just want some opinions about if this seems out of wack, inordinately high, or if I should concern myself with it and if I should--what steps to take. Thanks!
