Thanks for the input guys.
With regard to the weight the country limit is 53.0 most of the time now so it is rare to get a selection below 57.0 kg.
My preference is to ignore short priced selns so I have been keeping my eye on the following for the last 8 days.
Original rules plus ....
Ignore ALL metro meetings.
Eliminate meetings in NZ NT WA. ( just a personal preference of mine. I don't know if they are better or worse).
Eliminate any selection below $5.50 on Qld tote.
The results are ..
28 selns 5 winners LS return 48 units.
Profit 20 units.
