How about these tags for my balanced level 7 count:
2 = 4
3 = 4
4 = 5
5 = 7
6 = 5
7 = 3
8 = 0
9 = -2
T = -5
A = -6
EV is True Count divided by 10, so if the running count is 32 in a 6D game after 4 decks TC = 32/2 = 16 then EV is +1.6%.
You have to account for the house edge too, so a -0.6 game off the top would yield a 1% expectancy at TC 16.
To make it more easy it would be possible to start the running count at -6 to make up for the house edge.
You should expect very high running counts, I guess you need an IQ of 300 too.
