No it is better then a Marty, but still it has high risk. Near all EC-system tanks in time, do not need "long run". The reason it exist in prison, is that EC bet have high expose to the unfair odds.
However I test EC system, and with test I do not mean simulation, enough spins and it must tank.
But can I win some on it before it tanks or it is rejected, and it can take time, even Woodoo-system can win. Even on a Wheel with fair odds it is hard "in the long run" In a fair 50% chance the player who has the most money wins "in the long run".
It is a spreed of 1-20000 at BV Zero-Wheel and 1 to 4000 at the NoZero. Here we can last longer, but it is not impossible we reach the max.
I am up a bit in my trail, today it Went up 381 units which in money is Euro 3.81. Total it is more than 5000 units and about the same number of spins. I can not chip up, as just a bad run can be too costly. It is still a test. A betting system which last for many spins, gives very small winnings, and the turnover is large which is food for the HE. They use to get harder and harder to use, like they worn out.
