In the old days around 1912, they use this betting methods in Monte Carlo. many have noticed it is a bit more ODD/RED than ODD/Black.
The Surround methods in different set up, are using the same, and while trying to cover a lot of numbers make a higher hit rate. In fact using that RED/ODD overlap, is opposite to the idea.
In Monte Carlo they put a chip on LDOZ, one on RED, one on ODD, and one on the street 19-24.
They were flat betting as the first option, hoping for some break even spins until a RED/ODD in the street will hit, or a few winning spins. They target at 10 units.
I did a play, targeting ten units.
Another session, only flat betting this time.
The third session went 238 spins, win 21 units. Flat bet until low was -80. Then rise one each time a spin get minus, reduce one on spin gained plus. Max 5 in progression, went never down 100, and recovered, last spin made 30 units. Total 21 units.
The method is not too bad, the loss comes slowly if not progress hard. A few hits on some red/odd in the LDOZ or the 19-24 street makes it up.
