Grilleau-Personal permanence is a simulation and analysis software. The software provides an answer to the question that often leads to insurmountable disagreements among roulette players. For this purpose, 2 groups are formed:

Group A:
Group A believes that a permanence-the notation of individual coups-must be done directly at the table; A bet is therefore carried out chronologically continuously, without omiting coups, and placed at the same table. The course of a game depends on the table permanence, thus time-bound and locationally bound.

Group B:
Group B, on the other hand, believes that the formation of a permanence is independent of time and place. The coups of a permanence do not need to be recorded chronologically or continuously, and certainly not at just one table. It can also be used anywhere at any time. This is the so-called personal permanence applied by players of the method according to Marigny Grilleau.

To determine if and when, how the Permanencies of both groups differ, Grilleau-Personal Permanence 4 players compete in a simulation.
Each player records exactly 1024 coups in their own way for the easy chances N/R, Pr/I and M/Ps. After 1024 coups, the permanence for each player is analyzed for frequency, appearance towards the mathematical target, and standard deviation.

This can be seen in the construction of a permanence that has a natural structure that follows mathematics. Grilleau-Personal permanence analyzes each player’s permanence of 1024 coups and creates understandable diagrams and tables.
