If you keep striking 5 losses in a row, then it's probably the method of selection.

The rules to the 9/4 are exactly as stated when I first read it. Nothing has been changed.

What I have done though is fine tuned one of many selection methods and use the 9/4, for side bets over time,for example.

Supposing the minimum bet is 2,then the series on the minimums add up to 115
Supposing to all the figures you add a 0, then 2 becomes 20 units, total loss then is 1115
Supposing then you half that again, so the 20 becomes 10, then the total loss is 575.

To do this all ya do is multiply the mimnimum by 2,5,10, or 100, whatever you want to afford.

It is still seperate to HOW one makes their respective selections.

BW is right in saying have 3 "portfolios" of 9/4 runs,in principle. Could be your 1st,2nd or 3rd favoured/rated selections.
Then why not just hedge the 3 if one goes to that extreme?
