Nearly 0.3 units/hr
NoviceSTL,
I ran two 400-million-round CVData sims for a SD, H17, DA2 game with a HiLo player getting 5 rounds to 1 hand heads-up. In each case, the player was spreading 1-10 in nickels, betting 1, 2, 4, 7, and 10 nickels at counts of <1, +1, +2, +3, >+3, respectively. In the first sim, he was using Complete HiLo (sorry, I forgot about using I18 only), and he was winning $20.28/hr. In the second, he was using HiLo in Running Count mode (again, with Complete Indexes), and he was winning $18.84/hr.
Thus, we can conclude that using TC rather than RC is worth $1.44/hr to a $5 bettor, which is 0.288 units/hr.
Hope this helps!
