My response has nothing to do with my own riding & training and that’s not what she was asking about. I’ve watched many of these classes and I have also had the chance to scribe them. Of course people do transitions late or slow to develop sometimes. Just like they do in any other class from Training Level to GP. It’s not an insult to say they do & not meant to imply that they don’t belong in the class. It’s just a markdown against the ideal.
Scribbler-- no they don’t have to be at CDIs but to qualify for champs they do have to be double judged (I think?). So the show has to at least be big enough for two rings so that there are at least two officials onsite already. I don’t think a one-ring, one-judge show can offer qualifying YH classes.
And they will typically have them first thing in the AM or at the end of day, or, after lunch break so that they can assemble both judges at one ring for the qualifiers and then open the second ring for regular tests after the double-judged ones.
At shows I get over to in California they do tend to be offered at CDIs and the quality of young horses is exciting as is the number of rides in each class. But even there they have them at shows that are not CDIs.
And in Arizona we have them offered at our regular rated shows in Phoenix & Tucson but here you might only have one competitor at each level, if that many. And it’s still interesting (to me, anyway) even if the horse is not naturally a championship-level mover, because the feedback is aloud.
So to your last comment the value is in getting that outsiders’, expert feedback specifically on the horse’s quality of gaits & potential to impress, with more info & explanation than you’d get from what’s written in the little boxes on the regular tests.
