I agree that getting $50 pops consistently is pretty difficult and my method mainly selects horses in the $10-$30 dollar range but longer priced selections turn up regularly and sometimes win.

I have tried so many filters with my basic approach but they produce worse results than having no filter. I used to have a simpler approach than I have now and it produced a small profit each year but in the past few years the value has gone with those selections and so has the profit. I have recently made small modifications to my basic method and do apply a filter of sorts now just to pick different selections from everyone else and so far so good but I do know that the run of outs will come. As I tend to go against the grain my method requires nerves of steel!

Basically I reduce the field to a few possibles and then back the longest priced of these a few minutes before the race. I just don't think I can narrow my selections further so I opt for longer prices knowing that horses win in proportion to their starting price.
