Thanks, Stugots.

To recap the rules:

1) 8 to 12 starters.
2) Outright top selection in Unitab ratings.
3) Last two placed-positions to be between 3 and 6 points.
4) Unbroken by a spell.
5) Minimum Place strike rate of 30%.
6) No Maidens, Hurdles and Highweights (races with Hurdle jockeys)

Jackact, there have been several selections whose Place strike rate has been under 30%. They have had a poor strike rate and were not in profit so I've filtered them out of the method.

Today's selections

Morphetville R5 no.5 - Silver Shamrock
Kembla R6 no.8 - Tully Endeavour
Belmont R1 no.6 - New Image
Belmont R3 no.5 - Beyond Repute
Belmont R4 no.11 - Strait Laced
