Enforcing after the fact would not save the horse that breaks down at the show but it would save future horses and serve as a form of training/warning. And it should be easier to do especially if you could get the show software to cooperate. USEF gets a report of classes per horse as part of the show report or uses their software to do it, flags any horses over the limit, and goes from there. If that happens at every show people will stop. And they could start with a pilot/data gathering phase.
Itâs similar to running student papers through plagiarism software. You wonât necessarily stop the student as they are plagiarizing, but you can penalize after the fact. Eventually you get a reputation as someone who takes plagiarism seriously and students will stop (or enroll in a different personâs class). Itâs not a perfect analogy bc no one is physically harmed by plagiarism and the student is penalized on the paper that was plagiarized, but itâs what I could think of. And plagiarism, like overworking a horse, is nuancedâitâs been said that plagiarism is like pornography: hard to define but you know it when you see it.
