Here is an idea that maybe of interest to those who like to have a stab at all up betting.

The idea is to keep aside 10-20% of the return, before all upping on the next bet.

That way, a punter will show, all is not lost if one of them falls over.

Example.
Based on even money results. Place betting.
We will keep 15% of Ret.
Bt--O/L----Ret-----Keep---NxtBt
1.--5.00---10.00---1.50----8.50
2.--8.50---17.00---2.60----14.40
3.--14.40--28.80---4.30----24.50
4.--24.50--49.00---7.40----41.60
5.--41.60--83.20---12.50---70.70 ......Total Keep Col $28.30
6.--70.70

So what we have here is. If.....

6th bet fails. We still Keep 28.30 (minus the initial 5.00 = 23.30 prof)
5th-----------------------15.80
4th------------------------8.40
3rd-----------------------.4.10
2nd-----------------------1.50 (minus the initial 5.00 = -3.50 loss)

One does not have to target 6 in a row.
It can be 3 or 4 or 5 in a row.

Cheers.
