Just following on from that theme, here's something you could think about:

1 - Saturday metro races only (Bris, Syd, Melb, Adel, Perth)
2 - Races of 1200m or more
3 - If there is only 1 horse in the race which last started exactly 7 days ago, it becomes the selection, providing it won or was placed at that last start.
4 - If there are no horses in the race which last started exactly 7 days ago, then look for horses which last started exactly 14 days ago. If there is only 1 in the race, it becomes the selection, providing it won or was placed at that start.

Yesterday's results:
BR7-8 Babinda Half UNP
SR4-1 Fooram UNP
SR5-2 High Priority WON $4.80/$1.80
SR8-4 Kincharm UNP
MR2-10 Ulfah WON $4.80/$1.80
MR9-5 Tesbury Jack WON $9.60/$2.20
PR1-2 Graduate Boy WON $2.00/$1.30
PR6-5 Wave Rock WON $2.40/$1.40

Yesterday's results may be a flash in the pan. Who knows? Anyway, whatever the case, after looking at the results of all metro races from yesterday, I have to say that what I thought many years ago still seems to be pretty close to the mark. That is that if you bet on Saturday metro meetings and concentrate mainly on those which last ran exactly 7, 14 or 10 days ago, you shouldn't go too far wrong.
