Whelp, there it is. So disappointing to see.
ETA: makes me wonder if there are ANY upper level riders and trainers that are truly good horseman, or do they all have sessions like this? And if so, are they one-off things that upon later reflection, they realize were bad and never do it again, or are they regular parts of training? Is there any UL rider worthy of looking up to and wanting to emulate at this point?
