The letter "R "system of course was a a bit of fun but dont disregard proven form factors /fitness and value as per my post.
What I wrote in the very good method posted was just basic form factors that actually work in the long term.
Everyone knows or should know the basics of horse handicapping.
Anyone who cant understand the very basics should learn them first and in my opinion very quickly if they want to make a success of betting.

Probably the very best place to learn handicapping is through the research of Malcolm knowles (in my opinion the best racing researcher in Australia)

Or at the very least subscribe to a reliable provider like Warren Block of the Wizard.(If you buy the Wizard online $5.50 the other 6 days of ratings and asessed prices are provided free.)very good value from a top provider.
