I think this is key to the Grail. One mind says 38 spins before a repeat. There have been reports of a number going 400+ without a repeat.
Years ago there was a guy who built trackers professionally (he had to give up roulette programming). According to his chart on average a repeat number often happens in 12 spins.
Who knows?

If I may bastardize your thread a bit............
While studying FLATman's 9 v 9 system, I noticed it is almost impossible to get nine splits in a row without a repeater. I never have. If we stuck to the FLATman philosophy and called the 1/4 split just "1" and bet .50 on it, would it not be the same as betting a number?
But to the topic, I think it is rather rare to see 12 unique numbers. Let's say it is not a common occurrence. Someone will say they see it all the time. Who knows?

I have seen a number sleep for 840 spins, so everthing can happen. I use mostly inside bets and count for a repeating pattern. Everytime i got decent winnings it is on repeating numbers.
Thats what I try to catch using M7 method. A number will statisical repeate in about 8 spins, but it is an average, which is the same as say red will cime every second time on nozero wheel.
Repeating numbers have good potential to be profitable.
If it’s a grail you’re searching for then consider the possibility that strong repeaters also hold some voodoo factor that actually causes a bit of drag on any numerical neighbours.
So if #7 is repeating strongly it will often drag #6 and #8 along with it for a few hits.
The only anomaly is #36. Because there is no #37 on the wheel you must use #35 and #0.
