Hold up! Equitation in hunter world isn’t about posing over fences either. Not sure? Build one of the Medal courses (which they used to publish, measurements and all) and see how easy that is, or if you think just posing over fences is all you’d need to do to get around.
IMO, we could make eventing safer and more pleasant for the horses if we valued technique over git-r-done on the cross country course. When I was a kid, a rare clinic with Jimmy Wofford in NorCal where I lived opened my eyes to this. He praised the “show ring basics” in the smooth-riding kids in that clinic. And I have to say that good equitation basics kept me safe when I was eventing and field hunting.
Equitation has always been intended to make better horsemen of riders.
