Rule 1: Must not be carrying any more than 58kg.
Rule 2: Must be ranked in the top 60% of runners when ranked by average prize money. (For example, in a ten-horse race, consider the top six runners.)
Rule 3: Ridden by a top jockey (a jockey is one with a strike rate on the jockey tables of 6.0 or less) or a jockey that have won on the horse before.
Rule 4: Won on track condition (if slow or heavy track is involved).
Rule 5: Last run within 30 days unless good fresh record.
Rule 6: Win percentage greater than 20%.

sentabool comments: "I don't necessarily use all of these filters for all methods - it's a bit of trial and error but generally they have served me well.

"Also what I tend to do is if a selection fails on the filters I don't discard it as a bet - just throw it into a "speculative" category with a largely reduced bet - sometimes only $1. Over time this allows you to continue to monitor the base selection method and the impact of the filters. I have trashed many selection methods using this approach (and saved lots in the process)."
