Hey folks! Question!

According to Norman's Modern Blackjack II. you need stop hitting 10 vs. 16 on a running count of plus 17 (that's what the index chart says)and above right (versus 8 deck game)?
According to KO (Vencura and Fuchs) You must stop hitting 10 vs 16 on a running count of plus 32 (i start counting from zero) in 8 deck games. Since both system use the card of 7 as a plus one i am a little bit confused now regarding of this matter. Which one shall i use?

Cheers guys for the replys!
