Hey guys, looking for some advice once again.  Just ended a 17.5 hour session.  I am in the middle of my biggest drawdown over a statistically significant sample size.  I'm wondering what all you would do in this spot?  Play lower volatility games, only hold em and no omaha, take a break, or grind thru?

I don't have tilt issues really so I'm a firm believer that taking breaks is sort of overrated.  Although I feel the last 2 weeks I have made some speweyish calls/raises that are leading me to believe that perhaps I am not playing my A game 100% of the time.

Any of you math guys want to chime in and look at these numbers and see if they fall under the normal volatility curve or whatever?

I have a logged sample of 1000+ hours. I would say 75-80% of the time spent playing is NLHE, and 20-25% is PLO high only. I play 115 hours per month. Of those 1000 hours, I'd say 10% of them are in a casino setting, and 90% are at home games. The home game rake is 15 dollar max. (I know, crazy...I live in Georgia) The blinds are 1-3. but I would say it plays more like a 2-5 (or sometimes bigger) based on the frequent straddles and money on the table .My observed hourly is $45/hour over the 1000 hours. Within those 1k hours I had a 300 hour break even block where my hourly was -$3.72.=(

Now it gets nasty....In the last 69 hours I have lost 13k (previous biggest drawdown was 6-7k.)  

I would say 30% of those hours were playing PLO high only with a 5 and sometimes 10 dollar bring in.  I would say 8% of those hours were playing shorthanded PLO with a min 10 straddle max 25 button straddle.

Is this volatility due to the slightly higher PLO stakes I have been playing?  I'm not sure, I feel it's a combination of both variance, and poor decision making.  Your thoughts on standard deviations?

(Note: I am sufficiently rolled to be playing these games, even after the 13k hit.)

thanks!
