OK, I've codified today's selections into a set of rules:

Here's the plan:

We target the runners numbered sequentially to the highest numbered Radio Tab tip. If Radio Tab picks #11 then the target horse is #12.

However, if the target is the bottom weight, the next UP the list becomes the target. Eg. Radio pick is #11, the bottomweight, so #10 becomes target.

We move down from scratchings. If the Radio pick is #4 and #5 is scratched then #6 becomes the target.

The selection rule is:

If the target horse has barrier advantage over the Radio pick, select. If the Radio pick is barrier 8 but the target is barrier 4, the target horse is a selection.

However, two other rules apply:

If the target horse is rated 100 on the TABQ, select.
If the target horse is barrier 1,2 or 3, select regardless of barrier advantage.

Back each way.

I'II stick with this plan for a while and see how it goes. In my past race samples for these rules , 410 bets for $496 return, counting wins only. See how it goes over a week of live races.
