For the Hi-Lo I-18 Fab4 sim, the chart states that the EV at TC=1 equals .48% w/6D DAS DA2 LS 75% penetration. At TC=0 the chart states EV equals -.31%. This is a net gain of .79% in EV for only 1 unit of true count. This seems a bit on the high side. Shouldn't the EV be closer to .17% at TC=1?

It is a well known fact that each unit of true count is roughly equivalent to .50% in EV. The house advantage off the top is .33%. So, at TC=1 the EV would equal .5%-.33% = .17%. I realize the advantage per unit of true count is not linear, but it gives a good ballpark estimate of EV.

It seems as though the chart is overstating the advantage at TC = 1 by .48% - .17% = .31%. Can somebody please explain this?

Thanks,

MJ
