Hi Bhagwan

A bit more restrictive but some years ago there was a method which only looked at:
Sat meetings
Weekend Australian
The top of the tipsters poll (consensus)
Must have a score of 20
If none on 20 then 19
There were some rules which i can't totally recall.
The prices were short but it had a place strike rate.
It was bet at 1 win 4 place and made a profit.
With you research tools you may be able to mould something or improve it.
