As a genuine scientist numero intrigues me this, so I took the acid test of this simple system. Seed Capital € 500 per table, divided into five sheets of € 100. Invariably I put a counter on the first and last 12 digits. In addition, a chip on the first 18 digits. With this project, only the numbers 19 to 25 me an abomination, because then I lost my entire stake = € 300. Were the numbers 1 to 12, I had € 100 profit. At 13 to 18, I lost € 100. From the number 25 is no gain or loss.
If 0 was, it took me 150 euro because the casino than 50% of stakes paid. Loss is € 150.
Once I gain on a table had made, which with this game system is not right that you say about tip a, I switched to another table and played just as long until I am totally a gain of 200 or 300 euros had made. Then it was stop and go. I always had a buffer 1500 euros in my pocket.
This system is usually OK, but there were casinos, that I lost a few hundred dollars went home, but on balance I won. This system can only work if you have nerves of steel and do not let blinded by profit. The longer it takes before you make a profit, the greater the chance that you will take risks and deviate from the system. That's the trap of greed and the most difficult to control. In order to come up a little capital, you often visit the casino. Sometimes I stood outside again within 15 minutes, but with a few hundred dollars profit.
