Sounds useful. I wish it would also emphasis which aids are necessary for each movement. It would be helpful for those of us who don't have trainers.
The EquiTests do sound neat and useful; but I hope this doesn't encourage the use of handheld digital devices on horseback, or even really around horses. I once saw a woman riding a beautiful young grulla horse (in an arena, thank goodness), yakking away on her cellphone. Not only is that stupid and unsafe, but really, when you're riding, you should be giving your attention to your horse, right? I dunno about anyone else, but when I'm riding, I want to be concentrating and enjoying the ride. Neat idea though, I'm sure it will help many (non-mounted) riders learn their dressage tests better.
I love it!! Perhaps you could have a CODE for those of us that use the tests for the disabled in Special Olympics, Challenge Shows and Para Olympics. We are always low on funds. Blessings,
