Betting on the last five numbers to have hit is NOT an AP play. I'm not sure as to why you keep bringing that up. My point to it was that it is the one way by which a player could theoretically ever so slightly reduce the house edge if the player was on a live wheel and had no information about the wheel. The reverse is also true. Meaning a way the player could theoretically lose at a rate that could exceed the house edge is to bet on the numbers that are the coldest or that haven't hit in a long time. Again, this would only pertain to a live wheel.
Regarding the system of betting the last 5 numbers
, I use a similar system (not my best system), with great success. It all depends how you execute it.
We take the last 5 UNIQUE numbers (no repetitions among themselves), and bet on those numbers.
Needless to say that since we bet the last 5 numbers, we add every new unique number on the list while we drop the oldest from it.
That way we always bet the last 5. If one repeats the system wins. Then wait for 5 new unique numbers and start the process all over again.
I made an example of this system. I separate the 5 unique numbers with horizontal blue lines.
A blue dash indicates a losing bet and a checkmark a winning one.
Looking at the picture you will notice that a winning number spins in unpredictable intervals.
Ranging from an immediate repetition to 10 losses before a win.
Looking more carefully you will notice that the most frequent winning range
the 3rd and 8th bet.
And that agrees with a long time research that I have done.
And I have seen no repetition for 15 spins (though very rare).
Given that the most frequent winning range is between bet 3 and 8 I bet only that range.
Giving up winning opportunities if a win occurs in the first 3 bets, and at the same time being protected from the cost and heartache of a long progression that doesn't seem to score a hit.
Observing many roulettes, it doesn't take long to find a roulette that has already lost virtually 3 times or more, then all you have to do is bet within the range that had been found to produce the most frequent wins.
It is also worth noticing that a long losing interval before it produces a win, is not followed by an equally long or longer interval in the immediate next trigger. Rather the next win comes relatively fast. (Rare events do not occur consecutively).
