I was always under the impression that the trifecta will pay anywhere between 3 and 4 times exacta. In this particular case the tri payout seems about right based on what the exacta paid. I will typically look at the exacta payouts to see if something weird is going on. In this example, the exacta will pay would have shown me that someone is playing this exacta combo. I would love to go back and see what the exacta will pay was on the 2 favorites. If I see a low exacta probable on two horses with huge odds and combine that with a high exacta probable payout on the two favorites then that tells me that I need to look at those two high odds horses again for my win bet.
