This is based upon my opinion.
My first point.
One thing i been thinking about is to cut loses short, that the game is about not losing to much.
Then the winnings will take care of the other side of the coin.
Lets say i have 100 and win target 20.
Then if i don't reach my 20 direct ,,, and are down 20 i should aim to break even and not push for +20 - then i hade to travel +40 to reach that goal.
If i am down -20 i only have to travel to 0 and bet same distance as from 0 to +20.
This means i can reach my win goal twice with the same probability and distance or betting.
I regard +20 or break even as winning as there is no loses and get there betting the same.
That is one way cut loses short.
After that if i would be down -40 is time to accept loses or maybe fight back to -20 and stop.
As the distance or traveling/betting would be the same as the first indication to reach win goal or break even.
This is my line of thinking why we lose at roulette, we need strict and clever rules when it comes to money management.
And this put me to my other point of view.
My secound point of view:
I think there is a false positive thinking i can win 20% (a low win-target) to win more regulary.
Sure it cut loses short but i don't end up winning in the long term.
Lets say i win five days in a row +20 +20 +20 +20 +20 then the sixth day i lose my 100 and i am back at 0.
I gave it all back.
I belive we need to generate more money when we play and set win-targets.
Using a money management method that allow us to push for more with out giving it all back.
For example if i win +20 +35 +40 +25 +10 during five days and bust at the sixth day with 100,,, then i still have +30.
Because my win-target was 20% but i push for more and some time succed or hit saftey net.
The only method that allow for this is John Patrick and Brett Mortons Money Management methods.
I still read and learn from that and think that is very important to cut loses short.
I call this the 20/100 flaw that we have to overcome.
My third point.
Sometime i ask my self that we all develop ways to play roulette in the wrong way.
For example when you read gambling forums - then the most common thing you see is one bet selection and one progression - no more or less.
We know that will not work and still all continue in the same way.
My point is that we should start from the Money Management rules first.
For example i sett a win-target of 40 and that would make me happy.
Then i know what makes me happy and feel good to go home, the reason why i gamble.
Now the question comes what i am prepeared to risk to win 40
Lets say 200.
Here it comes, i have 200 and if the minimum bet on the table is 10 i only get 20 bets flat betting and less using a progression.
Now the Money Management tell me the rules and limits i have to deal with, i can not use any kind of sloppy method.
The staking plan has limits and same goes for bet selection.
So i can not just create a mehtod with a 12 progression.
No one start from this end when developing methods.
