Out of interest I looked at the relationship of TAB No.1 with Unitab's ratings.

If No.1 had been backed each-way from Sat 1 Dec with only three simple conditions:

1) Must be sole Unitab 100-pointer,
2) Must have placed at last start,
3) Not resuming from a spell,

then the results using Unitab divvies according to my reckoning are 25 selections for:

11 winners for a profit of $6.90,
20 placegetters for a profit of $4.90.

Admittedly this is a very minute example but it might be something to pique one's interest.

And if the following had been layed:

1) TAB no. 1 that has 93 or less Unitab points,
2) Not won last start, not resuming at last or previous start,

then, according to my reckoning there were 38 smiles for one accident of $1.90. However if I applied a filter which I use for my laying outsiders method (minimum of 9 runners) then there would have been 23 smiles from 23 selections.
