Maybe it’s a disconnect from the reality for jumpers? but for hunters… I can’t tell you how many times I’ve been at barns where it was excitedly brought up that a potential sale horse would measure as a small jr. The small jr divisions typically have lower numbers (which equals less competition) and usually less overall quality in that pool, especially when it comes to the horses’ stride size. That is, of course, a generalization, but that’s definitely the knee jerk perception of the jr divisions.
For jumpers… if I see a video and the horse looks suitable for the height I’m buying it for and the scope is there, I wouldn’t care. I feel like people look at the videos/photos first, anyway (at least I do).
