Unfortunately, the “gaits question” has been around and unresolved for many years. I remember talking with Dr Max Gawhyler back in the 1980s! He was especially concerned about the scoring at the lower levels where there were not enough trained movements to overcome average gaits. And that the idea of good gaits was being distorted and rewarding flashy but incorrect gaits. This was when warmbloods were first being seen in lower level tests and a lot of them were not correct as ridden by their ammy owners, but the mathematics of the judging system and the test (along with a certain amount of awe from younger judges) let to them scoring well.
I audited an L program and was interested to see that they do start with the gaits score. I would have less of a problem with this if it was really only correctness of gaits, but it seems more about scope and “brilliance”.
Interesting that the training scale is not really the basis for the judging protocol. I would much rather have the judge starting with a score for rhythm and suppleness!
I also wonder if USDF or FEI have ever analyzed the mathematics of the test. As I teacher, I knew it was all too easy to make a test that did not fairly reward the students with the best grasp of the material. Perhaps the USDF could look into that and tweaking at least the coefficients or scores for transitions etc.
The difficulty in rewarding, for example, big but tense gaits at the lower levels is not just that the correct but smaller-moving horse has trouble competing; it is that the flashy horse can continue on while missing some basics until they find trouble at the higher levels.
