I have used it & it makes good money.

It wont work if they all pay exactly $3.25

That is the min div, not the average.

Example.
10L x 1 unit = Loss -10
then
1.5L
1.5L
1.5L
1.5 x 3.70
1.5 x 3.70
1.5 x 3.70
1.5 x 3.90

O/L 20.50
Ret 22.50
Profit +2.00

+.90% increase on bank. Start again

+9.75% POT
4 from 17 = 23.5% SR

Level stakes =O/L 17
Ret 15
Loss -2
-11.76% LOT


Try it out on races with ,<=7 runners the first 2 favs & delete one of them using your favourite filter.
Only bet if 3.25 min can be had.
Easy.

You don't have to believe that a staking plan cant turn a negative into a positive, just because some one else told you so.
The same people will also tell you, that you cant win on the races.
So do you believe that also?

Just to prove it to yourself , start laying those selections & see what happens next.
