La Bouchere based on probability and odds of repeated numbers in 37 spins

Nice. From my testings now, betting last 18, (with an ordinary Neg. progression) it had about a 90% winrate. WG+2000, SL-2000

Awesome, Ignatus! But wasn't it suposed to  wait until 18 different numbers and then start betting?

I coded the Labouchere and Reverse Lab for ECs on Excel.  I'll try to find the file and will adapt it to straightups

The first 18 unique numbers appeared after 25 spins.
So we start betting at the 26th spin.

Wins: 192    (45%)
Loses: 233   (55%)


An important drawback: there are two big stakes of loses (one stake of 11 spins and one stake of 12 spins)
Of course Labouchere can beat this long-tome but he betting wil rise too much.
Any idea of a softer negative progression ?

[Roulettebeater]

There is no way - either you employ the labouchere which needs at least 33% wins or any other negative /positive progressions.

[Steve]

Progression doesnt change anything. Its just different size bets on different spins.

[SWEET]

You will never have more than 10 loses on the next 20 spins because it is Impossible to come up with more than  10 unique numbers

you said, no more then 10 losses in 20, but now there 11 losses in row?

[SWEET]

Huskerdu,
After observing your small sample of win/lose, we can see a tendency to streaks...thus I suggest you do more testing.
The most important issue is, whether this bet selection is stable, or always hit within math-expectation, in say, 100spins.
Stable or math expectation, mean in every, say, 100 spins, the win not below 40hit/100spins,
then, progression, of 1x20spins,2x20,4x20,
8x20,16x20, restart at first profit,
may always recoup initial losses, (of string of long losing streak) when long string of long win, hit.
Thanks.

[SWEET]

the other progression bet,
if you patience , wait for long streak of losses, (as variance avoidance), say, wait for 5,6,7,or 8 losses, then bet with progression

[huskerdu]

Hello SWEET
Sorry for the delay
I was just testing some more hundreds of spins yesterday.
Well what I saw was that there are always some strings of 7, 8, 9, 10, 11 loses.
Not often but there are.
So I think the best way of playing safe is what you said with your last post. Wait for some virtual loses without playing and then bet
Thanks so much.

[nottophammer]

Then the resident experts will say whilst waiting you could be winning.

No pleasing some

[Roulettebeater]

Husker

how many tests have you done? perhaps it is too early to say that max 11 spins can loose in a row.
given the fact that you are betting 18 numbers, the longest Losing Streak has recently reached 27.. be careful.

[SWEET]

Huskerdu,
If after, very long spins testing, and the result still very "streaky", and the win lose ratio, still "Stable",
then playing *follow-the-last*, or follow2nd last, could take advantage of the streaky with progression bet, but the *stable* outcome....most important.

[thelaw]

Would a reverse La Bouchere catch those streaks?

[SWEET]

Would a reverse La Bouchere catch those streaks?

Yes!
As long as it remain streaky, then reverse, definitely win.
The main problem,
is how much you willing to lose, eg. 1 unit, 2,3 up to hundred unit!

start with,(1), or (0,1), or (0,11111...up to hundred), depends on your risk appetite.

Thus Huskerdu needs to make very long real bm casino data testing, to see if his ideas, hit "STREAKY"...
thanks.
