Actually the run of outs was quite moderate whilst I used it though it may have fallen down later without my knowledge.

It certainly could be improved upon with sound logical principles common to most winners.
i.e Class horses in the top weight brackets.

Good jockeys and sound apprentices
Horses who lead or race on the pace ( especially at the distances specified by Ahjay)
Good win % ers
Top 4 Place %
Won over Distance and prevalent Track Conditions.

etc etc

Now there,s the bare bones of a system in itself.

Cheers.
