I'm sorry to say, but your good friend will wish he had never heard of staking plans if that's the approach he is using .

All selection plans , no matter how good they are, have runs of outs.
I feel your friend will hear non of that.
I feel you may have lost him to the other side, called La La Land.
You could try & catch him, when he returns back to Earth

Here is something similar, following the UniTAB tipsters.
It has it's good days.

RULES
Target Radio TAB Top 2
Target Late Mail Selection.
Late mail selection has to match one of the Radio TAB Top 2

Must be 2.60+

Staking plan that can work, if things go our way.
1 1 2 2 3 3 4 4 5 5 6 6 ect
Bet along the ladder, win or lose, until in profit.
Then start again.
