MY suggestion: not use automatic option given by betfair.com.
You can get worst odds (since meanwhile they change and become more profitable).
You can "GREED" your three options with an equal percentage equally distributed.
You can't adapt your betting choice (like more money on Team A and not Team B)
I used GEEK TOYS a sw created ad hoc for betting purpose

much much more efficient then classic cash-out option in betfair
[Now I can't use anymore since Italians can't use betfair.com thanks to our "monopole" in betting games
