Tested FLAT BETTING in 9.000 Live spins in Dozens and Columns and ended up with almost 0 loss 0 win.
In other words the -2,7 was gone.

Formations :

123/321/231/312/213/132=Run (R) sign
121/232/131/313/212/323=Change (C) sign

we bet after 3 signs have formed and from there continuous play looking always the last 3 Signs

Betting selections:

RRR= Bet R
CCC= Bet C

RCR= Bet C
CRC= Bet R

RCC=Bet C
CRR=Bet R

RRC=Bet C
CCR=Bet R

Clarification:
The repetition on the Doz or Col does NOT count as a movement(Formation) and its always a Win.
We are betting 2 Doz or 2 Col in every spin.

Well here is a SIMPLE system for you guys.
The system is so simple that you will blow your mind.

Start tracking the Dozens and Columns and R/B and O/E.
Start FLAT betting the selections that have the most hits.
we are ALWAYS betting only 1 doz and 1 col ...Never 2 of them.
In some spins some of the selection will be equal so do not bet these selections in this particular spin...

In 20 spins STOP.
Gather your winnings (of little loses) and start a NEW 20 spins session.

The reason why this wins.

In the short run(20 spins) the imbalances are almost always there.(Law of the third etc)
So by trapping them fast(short run) you make money.
In my testings the 20 spins cycles produced more wins than the 30 spins cycle.

The winning session average is about +10.
The losing sessions average is about -5.
The winning sessions are more than the losing ones.

Our goal is to make steady money overall.

30 chips  is the BR.

Hello.
I will now tell you how to win the ECs.
No clues , no nothing. Just the way.

Make 4 different tables on your paper .
Each table must have the runs and changes of the ECs.
every event must be compared with the LAST EC.
So 4 events = 5 last ECs.
Do NOT , I repeat do NOT care about HOW MUCH the deviations are.... care ONLY about HOW MANY the deviations are.
When you have 2 or more deviations bet for balance.
If you have 3 and 1 = 2 so bet
if you have 2 and 1=1 so do NOT bet
If you have 2 and 2= 0 so do NOT bet.

The reason why this wins is because 1 deviation can go as much as it wants.
BUT a lot of deviation events can not happen at the same time.

Remember that the LAST EC  must be compared with ALL the 4 events.
