Thank you Larp but that's not what I meant. I will try to be more clear in the example.
Horse Fav at start ... not yet betting
Favourite horse at start meets requirements ... bet
That's how it is now, I want it to be:
Horse Fav at start ... not yet betting
Favourite horse at start meets requirements ... bet
BUT if favourite horse was not favourite at any time during the race ... don't bet
Is this a better way to explain it? I know my English is not the best
