Let me see if I got you right on this "system" which basically every gambler with an above average IQ has played since the wheel of roulette was invented with an available racetrack on the table.

You are ready to risk 300 units for every 100 won. That means you accept a win-loss ratio of 0.333 to 1. Such a WL means that for every expected win of 0.333 units, you are willing to to risk 1 unit. Not very bright if you ask me.

Additionally, your participating odds, via this "system", are two five-unit neighbor bets on a wheel with 37 slots.

The odds for a win at any given spin are; 27.027%

So. To recapitulate. You have, probably without having made a single probability calculation on your latest "system", devised this ingenious way of making money from those slimy casinos, now potential suckers when facing the WOF (cocker spaniel?) where any given gambler, applying the horrifying bark of WOF, WOF...has a 27% chance of winning 0.3 units every time he takes the risk of betting 1 unit.

Hmmm, that is really a shocker. I am sure the Casino Managers are shaking in their offices, putting up DOA posters on your name all over the casino walls. I take it game theory has never been your forte.

* DOA - in wild west times, Dead or Alive, or as used in recent times, Deport On Arrival.
