Capital=All of your money. Investment= Portion of your money invested per unit ( day/month/hand/game) RoR= Odds that you will go broke RoR@X= Odds that your Capital will be less than Unit of Investment before reaching X. ROI= Return on investment, measured by percentage per unit of investment, represents your edge. Odds= Ratio of money invested to potential winnings. Equity= Portion of the potential winnings that is ours on expected value, affected by ROI. (1/2 for a coinflip 1/6 for dices etc…) Calculated by “Equity= Odds+ROI.Odds” This is only for calculating winner takes all scenarios. I have only figured so far formulas for situations where Capital=Investment. So if X= 2Capital Capital=1 Investment=1 ROI=3% Odds= ½ Then First we calculate our equity 1/2+3%/2 = 51.5% RoR@X= 100-51.5%= 48.5% So formula is RoR= 100%-(Equity) What would an appropriate formula that takes into consideration Capital to investment ratio be. I can only struggle to figure that there is a factor where the higher the ratio is the closer it will bring the edge to 100%: Following the same variables as before but: Equity=1/4 Then I calculate the reverse of the equity. Feq= 1-1/4 (? Is a mysterious operator) 25%+3%?factor.Feq 25%+ 99.999.Feq 25%+ 99.999.3/4 25%+ 75% 25 Somehow… My question is, what is the factor and how does it act? What would the formula be?
