I don't get that part? and pretty much don't get the rest of it either.   .   .    also why USD? why not just say units? I wonder if you are viper5?

as it has been said, scrap Martingale, use Lanky's divisor

Hi Jish,

My idea and experience told me,.   think of lost before thinking of win. 

There is one word very true, you will almost/ majority have winning edge (your bank roll higer than your invest) per section. 
The problem is always people not come out from Casinoi at peak profit but force to come out from casino after run out of money. 

For psychologically suggestion,.   someone call it greedy, how this happen? Example: When people put in $100, they may go down to 50usd , what is their mind is how good if they can get back that $100 only, but when they hit another usd$72 section, their capital now up to total of $120, then they forget about the pain of lost to $50 , and think $120 get it easily and very quicky.   when they have $120, they think another 30$ is easy, so want for $150,
this higher and greedy target never end , untill bank roll finish. 


What I want to explain above is, psychologically, people expect more and more money, and trend to stay longer and longer, so they way to protect them from run out of money is to finding way to keep them alive for longer time. 

Okay, back to above,
you can try to bet 22 number heavily and the rest less money, try on demo in internet. 

Yopu can see you get about 3/5 section earn back more than your capital,.   that is why I think this is a winning method. 


Beside, the chart of ball dropping zone is very important,. 

if the drop zone is 2 area and 3 area, this is good play, if active drop zone is 5 or 6 , that ius disaster,
and take note the hot zone center, there is some specifiec hot number in this hot zone.   make use of it. 

I have theory to sacriified 1 unit per number, sacrified 31 number and bet 6 unit extra on specified 6 number above all flat bet.   example,.   I put 2 unit on all 37 number, then on top of that put 6 extra on hot number.  /

Above, need to have 3 condifitin
1st the zone is fit and not moving little bu little
2 the hot nmumber apeal 3 time in 30 hit (also cover its neighbour)
3 The  monbey you get fo9r thiusn 6 unit extra is from earning, do not risk your pocket money. 
   if so try use 3 unit extra on 12 number (3 zone x 3 number at center of each zone)
My idea is, making 1 unit per section is too slow and can not saticued you to quit for the day. 

Making 2 x 35 unit 70 unit may mean something for you. 

Making 6 unity hit 216unmit gain minus other cost may leave 120unit for the day in 15 to 45 minute per day play. 

Do not start play if you not yert draw the ball drop travelling chart for at least 30 ball. 

Homework
Bet 20usd on 15 number , Plus another 6 number from 5 usd to 10 usd, total usd360 per game.

Have fun and win.
