I've decided if the fave is drawn in an inside barrier then to substitute it with the lowest barrier past the half-way mark.

Out of interest, in the previous post I mentioned that the method snares some large quinellas. Today at Goulburn R2 the method snared the winner of $53.10, the quinella of $190 and the trifecta of $16,000, and also the First Four. Sadly (?) I only had it to win.
