I don't know anything about that book, but I have found the most success with Professional Blackjack by Stanford Wong and Don Schlesinger's Blackjack Attack 2nd edition.
Professional Blackjack has all the indices you need to know as a card counter, and Blackjack Attack tells you the player advantage for a wide range of table conditions, bet spreads, and penetration.
For every increase in your bet spread, you increase your theoretical advantage by 0.13%, but that increase decreases in size the more you increase your bet spread, up until you reach Wonging advantage.

Thanks for the recommendation, but do you really not have the third edition of Blackjack Attack?
