I had a look at the TAB No.1 horses with yesterday's races. The rules I used were:
1 ) TAB no.1. Must be outright topweight.
2 ) Starting from barrier 1, 2 or 3.
3 ) Must be in the top three outright faves in the pre-post market.
4 ) Not resuming from a spell.
5 ) 8 starters or more.

The selections were:
Randwick R3 no.1. Won - $3.80 and $1.50
Randwick R4 no.1. Placed $1.50
Moonee Valley R1 no.1. Placed $1.90
Moonee Valley R3 no.1. Won $11.00 and $2.50
Cheltenham R1 no.1. Placed $1.60
Cheltenham R4 no.1. Won $4.30 and $1.70
Benalla R7 no.1. Placed $1.10
Grafton 3 no.1. Placed $1.20
Grafton R4 no.1. Won $3.40 and $1.50
Toowoomba R5 no.1. Won $3.60 and $1.50
Belmont R5 no.1. Placed $2.10.

From 11 selections there were 5 winners paying $26.10, and all placed paying $18.10. Eleven selections is a very small sample but at this time it might pay to look further. If there are any selections today I'll list them here.
