Doing some quick fiddling this gives a better result:

15.15% SR (13,000 selection)
-3.80% LOT

2nd to 4th on the turn last start
Won or less than 2.0 lengths from winner last start
Ranked 3rd to 7th on profit won last 3 starts
Career Winning Percentage greater than 15%
Age 4 to 7y.o
Metro Only
Closing Price $0 to $30

Note if you add in that the last start was within 10 days you get:

17.77% SR (2,220 selections)
11.12% POT (+247.7 Units)

Thats just with some quick fiddling and a database. Personally I think anything that has the highest prizemoney rank, win% rank, API rank or anything of that kind is pretty hard to turn a profit on. You'll hit a high % of winners but you'll drain your bank over time unless someone else can prove otherwise. I think if you look outside of these area's, while the win % is lower and you have to have the balls to trust your system in the run of outs, they will typically give you a better chance of making a dollar.

All my opinion but hopefully the above shows how easy and quick it can be to look even slightly outside the square and come up with a profitable angle.
