Thanks for your information, Chinbok. I don't have a database only because I know practically nothing about computers and would most likely be completely lost if trying to learn by correspondence. But many thanks for your kind offer.

I made a mistake with the rules - I should have stated DIST instead of TIM. Even then, I suppose a LOT of 7.5% isn't too harmful, and if City Best Tote as suggested by Partypooper is applied, then it might even have crossed over into profit. Again, its interesting to see with the neurals that Place is a better betting proposition than Win.

Hopefully DIST with Unitab 100-pointers might not fare too badly, and if it does then I'll be looking closely at filters, such as distance of race, condition of track...

Amazingly, after 5 races that have been run at the moment, four selections have placed for a return of $7.64 on NSW TAB.
