Hi there all.
Way back in the 90's I came across this trifecta system for 1200m race's, however I forget the exact formula but it goes something like this: ( By the way clarification of this system would be much appreciated if someone out there knows of it. I found it in P.P.M'ly.

1 Most popular horse in paper, Friday at 5/2 or there abouts

2 Horse with highest earnings - last race within 12 days, no less than 2.5 L from winner - Metro track

3 Horse that has come 3rd or 4th last race - provincial track ( Canterbury, Warwick Farm ) no less than 2.5 L from winner.

I have used this only as a stand out formula for trifecta's but would like to know the exact system.

One other thing... Dry on Friday wet Saturday - horse that has come 4th or 5th last race - 12 days - no less than 2.5L from the winner. I amm surprised at how many get a place. You know if you double $1 and keep doubling up... within 20 bets you'll have $ 1,040,000... more or less.
Oh, I'm knew to this... clever two legged human against 4 legged animal, sort of thing. Hope that got a laugh.
Best of best wishes to all.

Welcome
