From the book
The text below is what sparked my question. I always chip up when I see a large string of low cards come out of the deck on a single round, regardless of the true count. Therefore, I thought there might be an ounce of possibility here.
Plus-count wagering can be used when you are first counting in casino play, or when you are having trouble remembering the count while playing. With plus-count wagering, you bet more when there is any positive count from hand to hand. The procedure is to count the cards in play starting with a 0 count for each hand. This way you don�t have to remember the count from hand to hand. If there is a plus count, then you bet more on the next hand. This is somewhat useful when you are playing at a table with three or more players.
The advantage of plus-count wagering is that you don�t need to remember the count for the entire time between shuffles. This is less fatiguing and easiest to master. The disadvantage is that you will be betting inaccurately a significant portion of the time because you will be ignoring the results of previous hands. For example, if the first hand off a newly shuffled deck had resulted in a -3 count, and the second hand showed a +3 count, with plus-count betting you would bet heavier on the next hand because of the +3 count of the current hand. The actual net count at this point is 0 (+3 minus 3). You should be betting a minimum amount because you have no advantage. A much better betting method, and one that everyone can master with a little effort, is the running count.
