Default Re: What is your longest downswing/upswing due to variance?

[ QUOTE ]
I guess what I am getting at is trying to figure out whether my recent play against certain bad players is really just variance or not... obviously I have no doubt that I can consistently make money from these people because right now I am just killing them, but the question is, how much of my current return is variance and how much can I expect to have it continue?

I just started on a new site where the players are complete garbage, and my return over the first 18,000 hands is on average 9.55 BB/100... and that includes a long period where quite frankly I was playing too loose. If I just take the last 7000 hands where I have limited my play to peak times, switched tables at the right time, and honestly just played better, my return is around 17 BB/100, with one period of 2000 hands where it was 33 BB/100.

Now, I am pretty sure that the 2000 hand spurt of 33 BB/100 was variance, and I am also pretty sure that over 17,000 hands I can count on around 10 BB/100 (since that seems like too many hands for simple statistical deviation), but I'm wondering if 7000 hands is enough to determine the new (improved) rate of 17 BB/100, where I have limited my playing to peak times and improved my strategy. I can also say that I have had quite a number of bad beats that made me want to throw a shoe through my monitor, so it's not like I have been getting perfect cards this entire time.

Am I correct in thinking this or is there a nasty 25,000 hand downswing on the way? That's kind of what I was thinking about this... I haven't played that many hands online, so someone who has played millions of hands would have a better idea of this type of thing...

Edit: The more I think about it, the more these BB/100 numbers seem out of whack in comparison to what others are talking about - you mentioned 1 BB to 3 BB/100, and I am talking about 5-10 times that amount - yet that is what Poker Office is reporting... anyone else use that program and are these numbers correct?

My numbers are from limit. In no limit poker, using Poker Tracker terminology, a consistent winner could make between 5-7 PTBB/100 (double the big blind is a PTBB).

However, you are correct in surmising that it could be a factor of having the cards hit along with playing your cards well for maximum value.

If you are making the best decisions that you can, I wouldn't worry about the negative variance to come. Just focus on your decisions and just recognize that there will be a time when the cards will run against you.

You just can't predict the exact moment with certainty. Variance is determined by what happened and not what will happen.
