Beton, in my post yesterday,"Girls with Tatts" I highlighted the disparity between tote price and fixed price of the winner, $1.60 - $2.70. Have you or anyone ever considered this disparity as a pointer to the possible winner? Maybe you can program a bot to place a bet based on tote dropping to say 60% of fixed price. This way you would be free to do whatever else you want to do during the afternoon.
I never use the TAB so it might not be possible due to cutoff on fixed price bets, but it was just a thought.
With your proposed new research are you going to look for firmers or drifters as a signal? I remember a Forum quotation (CP, I think) based on records back to 2000 that 70% of winners were drifters in the market!
