Hermes - I may just be playing semantics here but I wouldn't call Testerossas idea a staking system in the normal sense of the term. If I understand it correctly what he is doing is generating a single lot of selections and then placing different bet types on those selections, namely:

1. Betting on each selection individually
2. Betting 2 race allups
3. Betting 3 race allups

Each of these 3 bet types (or 4 if you include the 2nd 2 race combination) is placed with even stakes. In this case the benefit is coming from the multiplier effect of the allup but as always the profitability depends on the POT of the basic selections being positive.

I have no problem with using allup betting to improve profits provided you have a positive return to start with (otherwise you will be increasing losses) and have a selection system with a high strike rate.
