Hi and many thanks.

It's very kind of you to send me the computed risk of ruin of my progression.

1)I'm a bit surprised by the high probability of losing.

My calculation was close to 1,20%.

Unluckily i'm not as good as you in software and computer ,even I have already download Octave on my MAC.

I have calculated 1,20% of losing all bkr, with a software of a friend of mine, based on Krigman formula.

Is in your simulation the partage option taken into account?

I have also checked with the informations of the following book: Roulette odds and profits by Catalin Barboianu (available on the web) and my result is what I said above.

But I'm afraid that your calculation is much more accurate,so I tend to trust your figures.

In both cases,my or your risk of ruin,is a progression that I must give up asap.

2)I have given a look to your OSBD 128MM table.

Very interesting,useful,but dangerous.

All my conclusions about roulette,that I have studied for 25 years are a bit disappointing.It's normal.

If you play even chance with partage option,you must play the lowest possible number of spin.

The best way of betting,from a mathematical point of view, is to bet the maximum allowed on a straight number.But you need a lot of money and the risk of beeing ruined is still there.

No roulette players enter a Casino and like the two examples above.

That's why I appreciate your yesterday table even if they have the goal to last more and to lose less,but not to win,it's impossible IN THE LONG TER:

Because the bet selection doesn't exist,now I'm am studying a way of playng that of course will lose but the risk of ruin is very far away,maybe behind my life of player or may tomorrow,but very very rare.

Of course the Murphy law is still there.

If you are interested I'll give you a snapshot of my studies.
