i realise you want a straight answer so i would say the closer to the winner the better.

just as a side issue ratings amaze me due to the traps they can lead you into.
i was watching sky this afternoon and after doing my horses (listed) they only listed horse running at sunshine coast was finnegan.
i decided that is stood a start of 10.577 lengths to the winner of its last start race.
this was too much so conceded it wasnt worth a bet.
then i saw the price odds on. and the caller had given it out as his best bet/
for those who saw it finnegan was last all the way and made ground when it was too late and finished a distant second.
in a 6 horse race.

i suppose if you look at a horse long enough you will be convinced it is possible to make a reason to put money on it.

but we shouldnt try too hard.
