Think I might go with this as a trial.

WON LAST 3 IN CURRENT CAMPAIGN

LAST START WITHIN 7 DAYS

WON IN TODAYS TRACK CONDITIONS

AGE 4 0R 5 YO MALE HORSE

NO 3KG CLAIMING APPRENTICES

Simple and should take no more than 5 minutes to get selections for all 5 states on a Saturday (which I,ll trial it on)
Those with a data base might give me some feedback.
Will keep a close eye on the longer distance races - those over 1600 M but will trial it over ALL distances.
Cheers
