What else would you want?
It was actually developed by Ralph Stricker, the 'Silver Fox', for Atlantic City multi-deck games. Arnold got Ralph's permission to include a discussion of this in his original 'Blackbelt in Blackjack.' It is not designed for single deck. It is effective for bigger betters as a way to mimic ploppie playing styles without hurting EV.
Ralph has not been barred in thirty years.
The idea is simple, the practice infinitely malleable. If you expect to more or less break even during neutral counts and place only minimum bets for over half the shoe, you are exposing yourself to scrutiny when your bets only rise during positive counts. If you vary your bets during these waiting periods, not only does it give you cover, but it does not help or hurt your EV. It does increase fluctuations and requires more bankroll. He says that "this is not detrimental to your advantage, merely worthless." The counter makes his money during those positive EV hands when you have a high probability of face card-rich moments. As a multi-deck strategy, it is designed to give you something to do besides looking bored and stupid until you get some movement on the count. Shoe games are much less volatile than other forms of blackjack. There are a variety of methods to vary your bets, including some rudimentary shuffle tracking and progression schemes. I will refer you to B in B for further discussion. I do not recommend varying your bets during negative EV hands. You should get away from the table or flat bet your preferred minimum.
If you are constrained by table minimums it is probably not for you.
The opposition bettor wins money by getting away with a large spread. Both Arnold and Ralph still endorse this type of camouflage for multi-deck games today, some 20 years after it was first put into practice.
