Hi Iomaca,
One way of using the Tab data is to use Qld UniTAB, target the TAB 1st & 2nd fav at 1 min till jump.

Bet them on Betfair if it is paying at least 1.5 pts more than the UniTAB.
Example
I bet Flying Along which was $3.60 on UniTAB it was carring 59Kg after just one race start, which it previously won , there were 3 other horses with the same wt & more. Its form to wt did not look good compared to the other more experienced runners in the field.
It Won paying $8.60 on Betfair.

It is considered amoung Bookies that QLD punters tend to be a little more astute than the other states when it comes to the punt.
One will see many winners that pay less on Unitab compared to the other states TABs among the top 2-3 favs.

If both the 1st & 2nd TAB Favs are paying 1.50pts more on Betfair, bet both of them.

Cheers.
