The "Permanence Personnelle"


Why you should record your individual spin sequence

As most of the roulette terms derive from French language this is also true for the topic we would like to discuss today. The Permanence Personnelle is a concept based on the theories of Marigny de Grilleau and can be described as the individual sequence of roulette spins one specific person observers during its lifetime roulette games. In this context it does not matter where exactly the spins come from or when they were drawn. The only condition is that the source of the spins is an unbiased random roulette numbers generator. That means you could watch a live wheel and note down the spin sequence. Then you could play on your PC a RNG wheel and continue to write down your Permanence Personnelle. Then you could take a book containing a collection of roulette spins, open a random page, and point your finger at a starting point and a stopping point and ad the roulette spins in between to your Permanence Personnelle.

The amazing truth is that your Permanence Personnelle follows the exact same statistical rules and produces the exact same results as if you would note down all the lifetime spins of a single roulette wheel from its first to its last spin.

If you use a system for even chances, let's say Red/Black then the sum of all your games played at different casinos will show the same results and streaks as if the sequence of spins would come from your private wheel just spun for you. Your longest winning streaks and losing streaks will, depending on the number of games you played, be of the same length as observed series of Black or Red.

In the same way you can use just every second, third or fourth spin of a wheel for your roulette game instead of the exact sequence of spin results of a wheel. The same principles and rules apply to this special sequence as to any other thinkable sequence of roulette spins. The statistical results will not show any difference.

Check out the following table of real wheel roulette spins from Casino Homburg. We have analyzed 37 cycles of 37 consecutive spins of specific roulette wheels, in each case starting with the first spin of the day. Known as the Law of the Third, you can calculate the binominal distribution for 37 roulette spins which results in 23,57 hit unique roulette numbers and 13,43 numbers that are not hit. Our results of each and every sequence are distributed around that figure as you can see on the right side of the table, averaging 23,7. Just as we would expect.

But if you analyze the spin results in the columns instead of the rows you get the same results. That is all the first spins of all the days and tables, all the second spins of all the days and tables, and so on. The results are displayed at the bottom of the table averaging 23,8. Even if you follow the yellow marked cells of the table from top left to bottom right or top right to bottom left you get the same results.

What can you do with that knowledge?

It is a good idea to keep track of your games and results in order to know where you stand in terms of deviation from the expected value. A MS Excel tool for tracking roulette results is available here. You can calculate the standard deviation of your Permanence Personnelle and your results by using the following formula:

Standard Deviation

Then you can compare your data with the standard normal distribution to see if you are around the expected average or maybe way above or way under the expected values. Then you can adjust your bet unit size accordingly in order to ride the hot streaks with higher bets or dive through the bad runs with lower bets.
