"From the beginning, this system is hopelessly confused. The text on Power Blackjack Numbers (I never did figure out what the "numbers" refers to) denies the existence of Card-clumping and then spends its time focusing on attempting (incorrectly, in my mind) to utilize clumping"

Power Blackjack Numbers seems to me to be watered down aspects of Blackjack 101 and Target 21, thrown into a blender with sour milk and lemon juice added. The taste isn't exactly objectionable, however, you probably would not want to make this a part of your steady diet."
