I wanted to revisit this.
Given pool size of $51,918, a $0.50 trifecta mutuel of $688.95, and trifecta takeout of 23.0%, my estimate for the number of winning $0.50 trifecta tickets is 58.
I estimate that a grand total of $29.00 was bet on the winning trifecta combination in this race - calculated as follows:
Amout Paid to Wining Ticket Holders:
Code:
AmountPaidOut = PoolSize x (1 - TakeoutRate)
or
AmountPaidOut = 51,918 x (1 - 0.23)
or
AmountPaidOut = 51,918 x 0.77
or
AmountPaidOut = 39,976
Number of Winning $0.50 Trifecta Tickets:
Code:
WinningTicketsCount = (AmountPaidOut/TrifectaMutuel)
or
WinningTicketsCount = (39,976/688.95)
or
WinningTicketsCount = 58
Total Amount Bet on the Winning Trifecta Combination:
Code:
AmtBetWinningCombo = WinningTicketsCount x BaseWagerAmt
or
AmtBetWinningCombo = 58 x 0.50
or
AmtBetWinningCombo = $29.00
Based on the above, I'd guess the actual whales collectively bet about $20.00 on the winning combo.
From there I'd guess the remaining $9.00 was bet by smaller players sharp enough to see at least one of the three horses that made it into the tri as a 'key.'
But that's only a guess.
Here's what isn't a guess:
It only takes a few extra dollars to knock down an otherwise high paying exotics mutuel.
