1) What exactly is the increase in EV to the player in a single-deck downtown game for using only Hi-Lo and a 1-6 spread vs. flat betting and playing BS?

2) What exactly is the additional advantage Rain Man can extract in that same game with the same 1-6 spread if he always knows the exact composition of the remaining deck and can instantly calculate the EV for each playing decision not only on the first two cards but after subsequent hits?

Thanks!
