Just to explain why I am interested in this. Over recent weeks I've set up a spreadsheet wherein I copy and paste (from Unitab) the fields for races of 1500m and beyond for Saturday Sydney and Melbourne meetings. I then compare all results of all runners to the par time for that track/distance/going.

Based on a figure of 100 with pluses/minutes etc for beaten margin, weight variation going into todays race, I come up with a rating for each runner. Only looking at races of 1500 plus, it eliminates first uppers. I then look at the improvement of each runner (compared to par times) over the last 3 runs, obviously leaning towards an improvement from 3rd last, 2nd last and last run.

My par times are the average of the ten best times for all tracks/distances/going over the last 5 years. My data base within my spreadsheet is now around the 4,000 mark.

I could pretty much use it for all venues throughout Australia on any day, but at this stage only doing Saturdays.

I'm keeping tally of my results for trifecta purposes for boxing the top whatevers. And also hope to hone in on a solid win bet by what I have outlined above.
