After 4 loses wait  for virtual win.

Quote from Bayes:

The progression is based on starting from a base of 1 unit and multiplying by around 10% - 12% to get the value of the next stake. Here is a version I just coded which is very similar to the Holloway progression using a percentage of 11.5% which gives approximately the same values and the same number of steps.

The error in the Holloway progression comes from rounding. You can see the same thing here: The middle column is the calculation unrounded and in the right column the numbers have been round DOWN to the nearest whole number. Notice that from step 27 (18u) to step 28 (21u) there is an increase of 3 units, but from step 28 to step 29 (23u) there is an increase of only 2 units!

Depending on how the rounding is done there will usually be some error like this, but it won't make a lot of difference. You could always change the values in the Holloway progression slightly to make the steps between values consistent.

24   13.633      13
25   15.201      15
26   16.949      16
27   18.898      18
28   21.072      21 << 3 from 18 to 21
29   23.495      23 << 2 from 21 to 23
30   26.197      26
31   29.209      29
32   32.568      32
33   36.314      36
34   40.490      40
35   45.146      45
36   50.338      50
37   56.127      56
38   62.581      62
39   69.778      69
40   77.803      77
41   86.750      86
42   96.726      96
43   107.850     107
44   120.253     120
45   134.082     134
46   149.501     149

In order to use such progression properly you must start with 10 units bet, therefore its increments of plus/minus 1 unit will be equivalent to 10%.
Instead of 10 you could use 25 as base bet with 2.5 as equivalent to 10 %, or 50 with increments of 5 as 10 %

I think for the most gamblers wouln't be so practical regardless of the effectiveness of the progression.

Long ago, I played this way
Using BVno Zero RNG and waiting for a trigger when the first 20 spins, we have the advantage of an event of 10 bets (12 reds-2 blacks), the begin betting on black.
Using the target profit 1 unit and stoplose -60 units. I make about 180 units with no lose ,after  4 loses waiting  for  vwin.
The strategy was very slow, about 3 triggers for the hour.
I know that at some point would be lost, but I do not have any program to simulate, so I stopped to play.
I do not know how behaves in long run , but  i  think it was just luck.

Yes.
I coded it and tested it with some different settings and - like every push till win type progression (what I know) - it failed surely, as usual. The Nemesis will come. Inevitable. Gratis: back-to-back, sometimes.  
I do not play with these kind of progresssions which can burst all of my bankroll in any moment. No Hope. (Just simulate enough, and witness fail.)

Can anyone post the Lou Halloway progression ?

I think it was a very long conservative progression.

Currently I'm not using it.
