I don't know if I can agree because often you don't know whether it is a good or bad system. After a downturn you could easily be chasing "bad money" and dig yourself deeper into a hole.

I knew someone who for one year (may even have been two) had a trifecta system which won him very good money, but the next year he just about lost it all.

You could have a "good" system but it still loses. The TAB deducts on average 16 cents in the dollar, which effectively means that to show the minimum profit your $0.84 must return $1.01.

As Chrome and Crash says, we must get good prices which is near impossible with the TAB.

There is an agency (can't mention it here) that gives the best Win Divvy of the three TABs for all meetings which is brilliant for Win punters.
