BB/100 variations question !
I was wondering this and, even if my question is maybe to general, I hope to get somekind of a answer from you guys.
If I have BB/100 of 6 after 10K hands, what is the range of my actual REAL BB/100 in the long run? Variation of 6? [0,12] How about 25K hands? 4? How about 50K hands? 3? How about 100K hands? 2? I ask this question to be able to go up a limit with, in theroy, a good confidance factor of beeting the upper limit without playing hundreds thousands hands. Thanks a lot guys. |

Re: BB/100 variations question !
10k hands is a fairly big amount for something like this. You wanted to find out how many BB/100 you normally earn, and you tested yourself 100 times.
Unless you've been getting a lot of good luck during that run, 6 BB/100 will be very close to your "true" average. Probably within 1 or 2 at most would be my guess. |

Re: BB/100 variations question !
I'd say that actually 10k is very little. Any upswing or downswing can change the result a lot. During 1000-2000 hands you could get so much "extra" from a good run that your winrate is inflated after 10k hands.
I would prefer to get 50k hands in before making any big assumptions. Anyway, if you do 6 BB/100, I think it is very likely that you are a winning player, but not so clear how much. |

Re: BB/100 variations question !
Assuming NLHE since it wasn't stated.
You're up 600BB in total. It's possible, thus, you could be anywhere from deserving -400 to deserving +1600, assuming +-10BI as a sort've "biggest realisticly possible swing", with a strong bias towards to middle. That's anywhere from -4BB/100 to +16BB/100 so you'd definitely need more hands to have an accurate idea of winrate. But your certainly a very strong favourite to be a winning player. |

Hrm, for some reason I thought I read he was playing limit holdem. If it's NLHE then yeah, more hands are definitely needed.

Re: BB/100 variations question !
I'm surprised that there were so many useless and incorrect answers.
You need to know your standard deviation, say per 100 hands. In NL, this depends more on your playing style than in limit, but typical figures are about 85 big blinds/100 in full ring and 95 big blinds/100 in 6-max. The latter is more sensitive to playing style than the former. PokerTracker reports an estimate of your standard deviation under Session Notes->More Details. In case you meant limit hold'em, the standard deviation is usually about 15 big bets/100 in full ring, and about 17 big bets/100 shorthanded. After n * 100 hands, the standard deviation of your win rate is (SD per 100)/sqrt(n). After 10,000 hands, n=100, so this would be (SD per 100)/10. A rough 95% confidence interval is the observed rate +- 2 standard deviations. I'll let you decide whether your BB/100 was big blinds/100 or PTBB/100, and determine your standard deviation. |
