The second simple system is one I came up with to begin dragging after the first win. I have used this successfully and, when the conditions merit, it is a good fall back system. It is a good “choppy” game system. The system is harder to manage at times due to its use of half units. Numerically, in units, it looks like the following:
1 - 1 - 1 - 2 - 3 - Repeat
As with Harvey’s system, once you lose, you flat bet one unit until you win. Once you hit the two-unit level, be more conservative.
The advantage to the system is that after each win you drag part of it rather than letting it all ride. A disadvantage is it will progress at a slightly slower rate. One more note about this system: when the deck seems to be player biased, the sixth bet could be increased to four units, then dropped down. Winning streaks of greater than six in a row are very rare, occurring about two to three percent of the total number of groups.
