Re: ROI in Heads up Sit and go
[ QUOTE ]
[ QUOTE ] After 400 games , you can only determine that you're likely to be within 5 % of your true win-rate . So if you've won 60% , then your true win rate is anywhere from 55% to 65% . If you want to be within 3% of your true win-rate , then you would need about 1,111 games . So if after 1111 games , your sample win-rate is 60% , then your true win-rate is anywhere from 57% to 63% . [/ QUOTE ] Isn't it true that the higher your winrate the less sample you need to accurately know your true winrate? Your statement above does not seem to account for that. [/ QUOTE ] Chicago , I'm surprised you didn't know this . |

Re: ROI in Heads up Sit and go
Yea I guess I confused the two.
I don't put a ton of effort into figuring out what my ROI could be if I'm running good/bad, I'm more into looking at the hard stats and fluctuations in my play in relation to my street by street stats and buyin levels. Thanks for clearing that up though. |

... In laymen's terms : ... Win-rate= [buy-in* Roi + buy-in ]/2 ... [/ QUOTE ] thanks for the response but i don't think your winrate formula works. I'm running at 10% in the 88 buyins, I just did the math plugging (88*10%+88)/2 and i get 48.4 that means i am losing more than winning which doesn make sense since i'm up 1.3k ???? |

Re: ROI in Heads up Sit and go
I expressed 1 buy-in as 1.05 units.
This is true as long as the rake is 5% . [1.05* 10% + 1.05]/2 = 0.5775 or 57.75% |

Re: ROI in Heads up Sit and go
The formula can be expressed as :
Win-rate = [1.05*Roi + 1.05]/2 Win-rate = .525*Roi + 0.525 So an ROI of 20% corresponds to a win-rate of 63% . |
