You are right in some of your tracks. I have run a quick test over tracks using a cut off of $15 for the top neural rater. $15 lay odds on betfair that is.

The following tracks had potential. The ones to the bottom are the better ones as far as laying (ie Albury is the best):

Flemington

Kembla Grange

Sunshine Coast Cushion Track

York

Nowra

Kalgoorlie

Cairns

Port Lincoln

Betfair Park Sandown Lakeside

Port Augusta

Penola

Kilmore

Geraldton

Albury

You will notice no Geelong Synthetic. Although Geelong Synthetic made a profit the likelyhood overall of a loss was higher as the odds on the nural top raters are just too high when at Geelong Synthetic. Same with the Gold Coast.
