Totally disagree with you that 5dimes has the right rules.
Prior to 2019, Ross Chastain would have been notified on Tuesday or Wednesday that his car was illegal and his win was being stripped. That’s it. There would be no elevation of the 2nd place car Moffitt being declared winner. In the record books it would still show Ross Chastain as the winner.
But for 2019 that is not the case. In the record books it shows Brett Moffitt as the winner. He is the official race winner. All 5dimes has to do is wait 60 minutes from the time the race is over to grade these bets. They are using antiquated rules.
