With A Modification Of The Contre D`Alembert Progression
Systems using flat bets generally contain long-lasting stagnation phases, which make a strategic play uneconomic: expenditure of time and the yield are in no profitable relation to each other.
Based on this realization and the fact that even money chances are ruled by both the law of deviation (ECART) and the law of balance (EQUILIBRIUM), it is quite possible to utilize the strategy of differential betting.
Differential betting strategy is not a bet selection or a progression, because it can be used only if two chances are attacked at the same time.
Differential betting can never be accomplished with flat bets since all bets would be zero!
Differential betting is only possible if two chances (for example RED / BLACK) are followed with a progression. Here for each chance, the respective progression bet size is determined separately, however, only the difference is wagered.
The Contra D’Alembert Progression System
The original D’Alembert Progression system is a negative or “up as you lose” progression. Starting always with a bet size of 1 unit, the bets are raised after each loss by 1 unit and lowered by 1 unit after a win.
The Contra D’Alembert Progression is a reverse of the original or “up as you win” progression.
The first bet of the progression is also 1 unit. After a win, the bet is raised by 1 unit and after a loss, the bet is lowered by 1 unit.
In the following example, we bet for ease of demonstration on EVEN numbers:
Using the Contra D’Alembert progression the spin run above would produce a total loss of 7 units within 14 spins.
In permanence sections where the deviation dominates, the Contra D’Alembert produces gains very fast, but the progression loses 1/2 unit per placed bet if the permanence balances itself out.
The same spin run using differential betting: · EU: units on EVEN · BE: balance EVEN · OU: units on ODD · BO: balance ODD · TB: total balance
The result of -4 is slightly better than the first result, however, is not very satisfying. Using a modification after a lost bet shows better results. The modification is simply to reset to a bet size of 1 unit after a loss. See the next table:
The spin run is balanced (7 even numbers and 7 odd numbers). The result is neutral.
Now let us take a look at a spin run with a stronger deviation towards one chance.
Here we use the chances BLACK and RED:
Since we do not know on which chance the deviation will occur, differential betting is obviously a good strategy to achieve gains be it a deviation towards BLACK or be it a deviation towards RED. The BLACK side loses 19 units and the RED side wins 29 units. Net gain of 10 units with the highest downswing of 5 units if you look at the Total balance. Seems to be not too dangerous.
