Playing with the SwongSim Variance Calculator but there´s a equation around
here and we can confirm these numbers, the equation goes...
EV ROI = ((((cEV+500)/1500)*((1-rake%)*buyin))-1)*100%
So lets take the $3 (8% Rake) Spin as an example, it would go $2.76+$0.24...
EV ROI = ((((43.60+500)/1500)*((1-0.08)*3))-1)*100%
EV ROI = (((0.3624)*(2.76))-1)*100%
EV ROI = (1.00-1)*100%
EV ROI = 0%
