I'm certainly no genius, hermes, but help this might be helpful to some.

The classic golden oldie overlay method is to make your own market and stake those overs according to the quinella percentages formula:

% = 100 / price A * (price B + 1)
+ 100 / price B * (price A +1)

eg 4/1 and 8/1 = 100/(4*9) + 100/(5*8) = 100/36 + 100/40 = nearly 3 + 2.5 so invest 5.5 units on this combination.


I like to get involved when the favourite is false according to my rated market and then I couple my other rated chances staked as above.

If only we could consistently accurately predict false favourites there are a hundred and one ways of making money, but quinellas is one way, I think, that affords particularly good value.
