The Superfecta payouts reported by Brisnet and Equibase are the payouts to $1 so that $493,651 Super payout on a pool size of $61,268 is normalized to $1, or $49,361 for $0.10. Undoubtedly someone or a few had a $0.10 super on the winning combo and won the $49K - nice! (And the Amwager mutuel result - top image - shows the payouts to $2, which can be even more confusing!)
