I really wish it was that easy. I have had horses that are dreams at home. They get to an inspection and the atmosphere is electric. They become very animated.
If you haven't run the triangle during an inspection, it is very difficult. You have to run as fast as you can (getting a long, lofty trot without breaking), next to a horse, turning with you on the outside (very hard) and go a long way. It is exhausting.
On one inspection, the stallion was acting up a bit. The inspector had me run the triangle three times. She was determined to have that stallion strut his stuff enough to get the highest score. I thought I was going to puke.
Do I think I could have jogged that stallion better? Probably not.
