As to why a good rider would oppose or want to skip a level, I'll give you an example. I prefer to spend my time/money/energy currently training and then bring my horse out at 3rd. I have spent the winter in Florida with my trainer. It has made more sense to do this with my young horse as he's needed to be challenged. I've ridden the other levels, and the bottom line is that my horse knows what the show ring is, and he doesn't need to go out and just show for the sake of showing. Been there, done that.
He's quite a nice young horse and he's a quick study, and is hovering right now between 2nd and 3rd. If I spend the time and get his changes, then he will be ready to come out at 3rd. If the rule were in place, I'd have to spend my time right now, to go out to shows, get points, and then move up. I like being able to do what is best for my horse.
IF the requirement are 20 points (it was discussed that it would be less) it still will require several shows to gain the number points, which just mandates showing and money in USEF/USDF pocket (not to mention gas, stabling, more adminstration fees, etc). Now, granted, it is a one time thing, but still--what exactly does it prove, since it does not PROVE good riding. If this rule, as it was proposed, is supposed to increase good riding, and stop poor riding, then I don't exactly see how this computes.
In addition, it takes the USDF quite a long time to get the show results posted on their website, so what if during the season a rider gets their required number of points? How will this exactly work. Will the rider have to wait for the USDF to verify, and if so, how will they expidite the process--or will the rider have to wait and if so, then be penalized because of their slow system. And if they end up getting a system that is faster, who is going to pay for it--the membership?
How much more expensive can dressage get? And, is it becoming more and more elitist in doing so? My guys are really nice expressive warmbloods, but some other discussions have centered around if this is going push average horses out of the picture.
