Not sure where I got this one from.

Highest Av Prizemoney

Last Run Won or Ran Within 3 Lengths of Winner

Won At Course AND Distance

Ist 4 Favs (Doesnt say whether OPENING Fav or at the Jump)

I,d assume OPENING as any mug at the TAB can back a horse into Favoritism
i.e "Follow the money etc

A lot of these systems leave important information out.
i.e Horse might be a backmarker and the race is 1000 M.
In a case like that you,d make a fortune Laying it .
