pk4 payout to the Travers

[OTM Al]

It's completely "fair" and "acceptable" because it's in the rules

4011.26 (h) Dead heats. In the event of a dead heat for win in any or all pick four races, all pick four tickets designating either horse to win in said race or races shall be eligible for participation in the remaining pick four races, and the net pool shall be equally distributed to the winners, that is, the net pool will be divided by the total amount represented by all winning tickets and the resulting price, per dollar, and after breakage, shall be the payoff price, which shall be uniform for any winning combination.

If you don't know the rules of a bet and you still play it, it's your fault when something like this happens.
