interesting points imagele.
i wonder had the race been at eagle farm or a group race at randwick how barrier 15 or 16 would go.

but the point i am interested in is at what stage do you stop including every horse as a chance. i have no doubt if the best horse in the race is drawn at 15 then its probably a no bet race.

theorists contend that the experts in racing have it sorted out like this.
in a 10 horse race all things equal there is a 11% chance of picking the winner
but the punters by weight of money have it sorted to 30% - 33% e.g. the fave wins this percentage the rest is luck.
what proportion of that luck is good barriers is the question.
dismiss it if you like but at the end of the day on most tracks it has potential.
my recent interest was stirred by the way shortpriced horses hook back in brisbane.
i will keep watching. good luck with your method.
i am merely sharing my thoughts with those interested in reading.
