What do the Statistics say?
On the following table you can see the system from the viewpoint of the probability and the expected profit:
|Spin||Probability||Profit in Series||Expected Profit|
Unfortunately, the expected profit resulted in a loss, therefore in the long term, the system should go below zero. Let’s have a look at the progression of the basic system on the following graph:
There was no point in altering the series length. It follows (from the table above) that as long as the series was, always the expected profit results in a loss (we had tested a series of 5 spins and a series of 25 spins). At the first sight, you would assume that there is a chance that you hit at least one number within 17 spins, but empirically based research had confirmed that there were also series when the roulette did not hit any number of a certain pentad 50 times in a row.
Applying the wait strategy would not be also supposed to have a success. We have attempted to apply at least a liner series progression; it means that after each unsuccessful series, we increased the bet size on each number by the value of initial bet and after making a profit we reset the bet size back to initial bet:
