Thought of something I left out-
Part of it may be related to the fundemental differences in how Eventing and Dressage shows work versus how H/J shows work.
In Eventing and Dressage there’s a greater sharing of information between the Judge and the Rider. At the end of the day, it is still “that particular Judges opinion of your ride at that moment in time”, HOWEVER you can look at your score sheet and see what the reasoning behind that 4 on your 20 meter circle at C was. You are scored AS you complete the movement - no time for the judge to forget if that corner was a little sloppy, that your courtesy circle was lovely, or maybe that your lead-swap was late. Everyone gets helpful comments (okay, sometimes they aren’t helpful), from the judges they show under and can track trends in their riding as well as personal progress.
We don’t have anything like that in the H/J world. Sure, we can ask for the judges cards at the show office, but so much of our judging comes down to personal preference. I can remember a thread about a short-stirrup pony in a pelham and the judge who was at the show eventually popping in to the thread and saying that they tend to not place ponies in pelhams due to it being a suitability issue. I’ve personally had a discussion with a judge who was conflicted about placing a really talented kid who put in BEAUTIFUL rounds but was unfortunately wearing a black jacket (sin of sins), and mounted on a very average, $2k good ol’boy and up against $30-50k pony hunters. The kid put down 8 perfect fences, landed on all of her leads, made every line - it looked absolutely effortless. The other kids had chips or late swaps, and the judge pinned them over her - why? Well, because as another poster pointed out when I shared the story, “it’s a horse show” and those $30k ponies are just nicer animals than the 14.1h maybe-a-quarab with the kid in questionable fashion. One of the sad and ultimately mockable realities of the H/J world is that at the end of the day, we do not have a level playing field. In the Hunter and Eq rings, where everything is subjective, the best ride doesn’t always win. One judge will pin the 10 jumper with a late swap over the 7 jumper with a perfect ride and vice versa.
We don’t get feedback from the judges in the same way other English disciplines do - at the end of the day, we can make educated guesses as to what we did to make ourselves more or less competitive, but unless we ask at every show (and are fortunate enough to get judges who write extensive notes) we don’t have a way to track personal progress other than by end-of-the-year points/awards or things we’ve qualified for.
Another related point is that in Dressage and Eventing there is some degree of ‘moving up’ or progressing thru the ranks. You CAN stay at the same level for as long as you’d like, but there’s a system that encourages you to move up once you’ve mastered a certain level. Our Adult riders don’t have a Maclay to chase. Some might say that the H/J world is a Junior’s sport. We continually make new ever-green divisions and tiny-tot fence classes in the name of accessability (or making money, your call) and are content to cruise around the same divisions, jumping the same eight fences, year after year after year. We top out at 3’ or 3’6" and never venture outside of that framework (“this horse is a hunter, we could never go do a jumper class”). Many people simply hang on our trainer’s every word and would have a heart attack if their trainer couldn’t come pop them over some crossrails before jumping the same course they jumped earlier in the morning.
There are a lot of wonderful things in the H/J world - we consistently produce some of the most amazing horses and riders in the world. We have many well developed show circuits that supports all levels of riding - from the backyarders to the top of the sport. We have USEABLE horses in Hunter Breeding, wheras many other organizations have horses that are useless after their Halter career is over. Riding 8 perfect spots and hitting the strides without a noticeable change in pace IS a challenge. Finding the balance between speed and accuracy is HARD. However, if we can’t look at the absurdities in our own discipline, we can’t improve. Looking at the stereotypes at least gives us a notion of what we should strive to avoid being.
