On average, 24 numbers come up out of 36.
So if we wait for half the numbers to come up on a 00 wheel, we will be up to 19 numbers.
So if we did a progression on the remaining 19 numbers for 17 spins (to make 36 spins total) then by the law we should hit 5 times.
But we only want to hit once, so we can reduce the number of spins from 17 to 13.
However, out of 19 spins, it is very rare for 19 unique numbers to hit. So for every repeat, it will reduce the number of progression spins.
So you could end up with a progression of 10 spins max on 19 numbers.
It would probably be worth resetting the progression on a win and catching all 5.
A 10 step marty on 19 numbers
Yikes
I will just ask the dealer to hand me the bullet himself
What is the lowest amount of unique numbers that came up in 35 spins?
I probably should clarify that I'm not trying to be realistic, but simply win on an acedemic level first, then with table limits, then refine to a more realistic system.
