I think the art of winning is finding your own "niche" I do not even try to pick a winner, I look for horses that are overs/value and back them, now when I say overs, my concept of overs is a lot different to most "experts" I have heard some say that they rate a horse a 6/4 chance and they can get 7/4 and they consider that to be "overs" to me that is ridiculous, that assumes that racing/punting is an exact science, I look for horses that I consider a 6/4 chance that I can get at least $4 I need a big buffer zone....and they are always there
as an extreme example of what I look for and how I find them, when Lunar Fox won the Australian Guineas I marked him down as a $15/$20 chance and backed him several times with the top odds being $500 (499/1) with Betfair, his recent run was ordinary but if you look at the forest and not the trees, this horse had had 2 previous "target" races, the VRC Sires which he won at good odds, beating Ole Kirk, then his next "target" was the Caulfield Guineas,(which was won by Ole Kirk) where he ran 5th not beat far but beating home Tagaloa who was Fav for the Australian Guineas, while Ole Kirk was well into single figures, so when he has a target he runs well, the next target was the Australian Guineas, I just looked at similar races, the rest had no relevance except to hide his "real" form, so if you just look at the Sires and the Caulfield Guineas, against pretty much the same field, what would you rate him? certainly nowhere near triple figures
Just today I backed a winner (Tinnie Winnie) I took $8.50 ($4.63 after deductions) it won and SP'd at $2.80
Another that I thought would start much shorter was Custodian in the Black Opal, I had $200 on him at $21, then laid him at $4.30 to get back $600 if he lost, so my worse result was a $3 winner($400 profit)
I would never tell anyone how to suck eggs, do what works for you, I never bet on anything but Thoroughbreds, cos that would be like gambling for real, I know what I know.....and I know what I don't know!
