Hi barny.

After doing all the filters to improve my ratings (ratings 1st mechanical 2nd
for me anyway you know them all.

1=Check last two starts starting price of each runner add them together.
2=Profitable form lines horses last two starts.
3= Is my horse firming or easing in the betting etc etc.

The one filter that drastically improves my (FINAL SELECTIONS)
is the country where the horse was sired.

You wouldn't believe how many losers i have saved betting on just
because my selections are bred in argentina brazil france japan etc.

The other side to it is in some states country metro prov i can safely,
contain my ratings to certain ones eg australia usa ireland vict metro.

Not sure why this filter works when so many others i apply are much,
of a muchness as i am certainly no breeding ************.

It MAYBE a filter to improves ones strike rate it certainly helps mine.

cheers
garyf.
