I had a mare that I evented and did dressage shows with, with some degree of success, and I can safely state that she was much less horse than Salinero. However, one year at the local recognized show, after the horse had retired from eventing and was in her late teens, something happened just as I was starting a test, and had halted at X and saluted. Next thing I knew, I was galloping back toward A. I managed to stop and resume the test before being eliminated, though the test was pretty ugly (got smiley faces and comments about my passage and canter half pass; alas, it was a second level test …).
Although the horse went back to doing respectable tests in every other way, I was never able to sustain a halt at X with that horse again, and it was not a situation that I was able to duplicate in practice at home.
There was a lot of speculation from people who had seen the episode about what exactly it was that happened with my horse, but we never nailed down whether it was the poorly placed overhead flags in the arena, the kids playing soccer on the upper level of the grandstands, or something about the late afternoon sunlight. Whatever. And this was a mare famous for being a baby-sitter for young horses on their first outings, for being a rock-solid adult-amature horse, for being sensible and kind and easy.
Horses are horses. If Anky can do well enough on the rest of the test to fluff the final halt, more power to her. But I can understand her decision not to prolong the agony for her horse at the end of her freestyle. If you squint just the right way when you watch, you can imagine that she’s just saluting with both hands … even though the halt is not maintained ;).
