As no one else has commented yet I thought I would give it a go.

If that is correct, that is a fantastic system however, a word of warning - UB's place data sometimes doesn't seem to be correct. You would need him to verify those results.

The other thing that I find with a lot of systems posted on here is that it will take you all day just to work out your bets.

The Rules used were :
Price Rank <= 2
API Rank <= 2
Don Scott Rank <= 2
Career Races between 5 and 10

What's that, 3 or 4 points of reference FOR EVERY RACE just to see IF you have a selection? The way I see it, you would have to write down all the top 2 don scott ranked horses, check whether they have had between 5-10 starts each, check their API rank (I'm not sure what this is or where you get it) and then sit in front of the computer all day and hope that they are in the top 2 in price rank OR input all the qualified selections into a bot with a setting to only bet if they are in the first 2 favourites (which will take forever to input if you have a lot of them anyway).

That's a BIG job. If you can somehow automate everything then you'd probably be onto something (if UB's data is correct).

I don't mean to bring you down but if you wanna go for it then good luck. Please keep us informed of how you are going.
