##### Math-U-Lette 28 Number System
« on: June 03, 2016, 03:12:59 AM »

That's 3 units on the dozens and a single unit on the splits.

With the dozens acting as a buffer, the max expected consecutive loss has been reduced from 124 to only 40.  That means we can expect to actually see one of the splits hitting AT LEAST once every 40 missed spins.

The max expected consecutive draw-down on 28 numbers is 13.  The theoretically worst draw-down possible before one of the splits hits is:

L L L L L L L L L L L L
w
L L L L L L L L L L L L L
w
L L L L L L L L L L L W* (split hits)

I personally think this sequence is practically impossible and will never be seen.  A more likely (but probably too severe) outcome is:

40 losses with 12-13 dozen hits interspersed about once every 1.3 spins.

Currently playing around with raising 1 unit on a loss (+1 each split, +3 each dozen) and either spinning back into profit from the +1 dozen hits OR one of the splits hits and I lower the chips to (TOTAL DEBT/10) chips (rounding up) and adjust the dozens to match.

It is reputed that this system was designed by a mathematician.

I got 150 units in about 22 minutes in the above video.

If you're lucky enough to find a game that offers the 50% rebate on a zero for evens-payoff bets, this system isn't a great idea - as all of the money is being exposed to -2.7% EV rather than a chunk of it to -1.35%.

There are 9/37 numbers left uncovered on each spin - so with 8 units pitched for each spin a fairly short run of the 9 bogeys will have a fairly hefty impact on the the chipstack.

Not a great example of a method that looks to reduce risk (of a losing spin) and money exposed, IMHO. I suppose it depends on individuals' threshold for risk?

Re your winnings, I'd say bank the money . . . .

The system is very interested and the betting scheme with the progression looks also beauttiful.
In spite of these the result is predictable. A short run trial can finish with a loss or a profit and a long run sample finishes with a loss of 2.7%. What I miss is a trigger, plan or strategy.

Bet 3 units on High,1 unit on a DS and 1 unit on a uncovered corner. The long run loss is less than 2,7%

Reyth this is great. Thanks
I also want to check Vitalis numbers.

Could please elaborate a bit on

Reyth,

Reythyou just got lucky . And I went straight losing streak .

Thank you for this awesome hard work!  I love this btw, this is the life blood of my hobby, collaborative work like this!!

However, I must disagree with your results as I am showing a profit of 45 units!  Granted, this is the worst draw-down I have yet to see (1161 units required) but the system recovered like I have normally seen it to do!

I also wish to note that a couple of times when profit was restored, I forgot to lock in profits and probably didn't raise as soon as I needed to; just a slight difference really but I think locking in all profits and thus protecting them is important!

Expected consecutive loss for 2 splits? Can you please explain in more detail your line of reasoning?

Yes, this is a concept that I am sure you are already familiar with.

This bet is really all about misdirection, where the dozens are there to absorb what would be miss spins from the actual target which is the 2 splits, as you have indicated.  Since this is the case, I ran what would normally be the max expected consecutive loss for 2 splits (4 numbers) and after 16M spins, the max consecutive loss seen is 124.

I then ran a comparative output with the two dozens counting as neutral spins, complete misses counting as a loss and either split hitting as an end of the loss streak sequence.  The total maximum consecutive losses after 16M spins was 40 (in other words, the dozens ate-up/absorbed/etc. 84 loss spins).

The concept behind this is that when the dozens hit (sponges, buffers etc.) it is like a free spin towards the eventual hit of the splits; it is as if the spin never happened -- gaining a unit is simply a bonus, icing on the cake etc.

I hope its clearer what I mean now?

Vidaly by analyzing the 61-70 spins of your demo I think you did not played correctly.
The numbers are:
10
26
12
25
21
11
23
22
26
15

Roughly speaking every dozen win should be about 1/4 of a loss and every split win should be about 3 x Loss. In your diagram your losses seem bigger for some reason.

I use not to be found of covering a lot of numbers on a wheel with -EV, and I use not to try progressions which are step on bets on a lot of numbers.

Then I did some spins on a NOZ and never use a progression, it took  270 spins (autospin in fast mode) to reach 100 units plus.

I saw a few moment with losses in a row, which would make down a lot if a progression was used.  Flat the balance goes slowly up or down.

It may work better if we use a softer progression.

I made a play on a zero-wheel, which return all outside bets if zero hits, and pays 37 on a straight. I then put three 0.1 chips on the two dozen, but as split pays as usually, but straight up 37, the bets inside were 0.05 on four numbers, the same as the splits 14,17,20,23.

The loss is still 0.8 on the  eight numbers, but just 0.2 on zero and the payout for the doz is the same, but  1.05 on the numbers.

Took 200 spins to climb up to 10.05.

I like the general premise of the 28 bet. I've been pondering double dozens for awhile, and the addition of the splits to the uncovered dozens is an interesting idea - it gives you a shot at a nice little payoff.

The way I've practiced with the double dozens is to bet that the dozen that has just shown will not repeat, hence I cover the other 2 dozens. I like the 24/37 or 24/38 coverage, but I still understand it's a "lay" bet (a lower payoff than the money risked). But, the near 2/3's chance that a covered dozen will win attracts me. I can hear the 'dozens are not due " crowd - sorry...but I freed up my mind some time ago - and started thinking outside the "next spin" box.

I might do some testing with the above method, with one little difference, being that as the dozens move... my splits move with them, rather than staying in fixed positions.

So, if I'm covering dozens 1 and 3 (like the example in the graphic) and the first dozen hits, I'll move my dozens bets to 2 and 3, but place my splits in the 1st dozen.

We cover a lot, so we will win as long the uncovered stay lower in hits.
Did a test on an other wheel. Which pays 38 on a straight, but has two zeros. Which means 0.2 loss on zeros,
0.8 on the uncovered numbers. We win 0.1 on dozen and 1.1 on numbers.

This time it went down 5 Euro and turning slowly upwards. I stopped as soon it was a plus, at spin 247.

Could of course not resist trying on an EU-wheel with full loss to zero. The min bet is just one cent and I thought trying 200 spins and risk just 300 cent.

Went OK, and the  54 cent plus after about 200 spin, shows the bet have some merit.
All test were done flat.

If we need a progression? I think so, win flat we can do, but the losing session will outnumber in time.
Could we find a not too bold progression, we will avoid to go too deep, it just have a few numbers uncovered, which would not dominate too long.
