The question of RIPPLE is incomplete (but we understand

) since the length is, in statistics, proportional to the number of spins. The gap will grow in proportion to the number of spins. There is therefore no limit in the absolute of mathematics.

I checked two months ago a dozen that do not repeat, this on 200 or 300 000 spins, I don't know !

However, the answer I can give would be incomplete for the practice if I don't speak of the indirect statistical discrepancy.

On my sample, I met the absence of my dozen 21 times and even 23 times. But there is worse with 29 times against 1 in 30 spins. This indirect gap is more devastating.

One can calculate the length of a delay on the dozens by multiplying by 1,5 the value of the déviations on the simple chances. The calculation becomes easy
