Several years ago, riding my mustang in a schooling show. Doing our 20m circle at A, halfway around she spots a jump standard someone has stashed outside the ring. She slams on the brakes snorting and staring at the “monster” for at least two or three very long minutes. Judge’s comment was “loss of forward motion.”
I have found that when your test goes to shit and the judge has to find something nice to say it’s “Elegant Pair.” I’ve received that comment more than once riding a tubby mustang who moved like a sewing machine at times.
