Hi dale

This is a excellent strategy i use this except i apply the opening on course fav

Combined with ones ratings or mechanical system it's a worthwhile pursuit.

Eventually some filters (MAY)improve it even further.

Without tinkering with the selection criteria i find these help.

1= state
2=country metro prov tracks
3=minimum price.

This is strategy one of trackmate a program i purchased through malcolm knowles inracing at one of his seminars i attended several years ago at moonee valley racecourse.

Good luck with the survey.

Cheers
garyf.
