Yes this system is a snail grail.  Have a  Bigish bankroll play on small stake live wheel and you win every time. I never lost a session to date , only problem is I don't have the patience.  You can be sat waiting over an hour for the number to hit which it always does.  One reason it works really good this method is because you are targeting a single dozen with many of bets.  

Just laughing at the guy who says ladbrokes rng is fair.  

Many guys have lost a fortune at that rng.

I am not saying ladbrokes are cheats , not for one minute.

Just the software they use on there rng is highly suspect. No one could convince me other wise.
Cheating software without any question ."mr ladbrokes protector".  
The way the software at ladbrokes plays against the player especially on red black betting shows to me that the rng is switching in losing bets and is not true honest random event.  If any bill gates computer expert was to delve into how rng's tick I am sure they would agree that rng can cheat.

Yes also RNG is TRUE, 37 numbers picked at total random on the other hand real wheel is open to many variations, humans, manufacturing, warping, ball velocity, spin, drop height.....

Not true. Hot and cold numbers do exist. It's knowing the reasons why they exist that is important. Sometimes numbers are hot for a reason. Cold numbers can be cold for a reason too.

 
The progression I now use is this one below. So far I have not lost a progression. Should you lose all bets in the progression then you lose 416 chips.
You win 93 out of every 100 progressions.
