As a relative newbie to all this malarky i have understandably been doing a fair amount of reading/researching from multiple sources. That said i recently discovered an interesting "fact" - i use the term liberally as i have no confirmation - that approx 80% of the time the winner can usually be found within the top four of the TAB market.
Is this accurate?
If so, how would a fella such as myself go about utilising this information to best advantage?

Any suggestions will be gratefully received.
