Wildspot, I think the reason your comments were received the way they were was because of the tone they portrayed: "You started jumping BEFORE you started cantering? ". I read that as "Are you a moron?" It may not be what you meant but you are forgetting, people pay their trainers for the expertise they have to offer. That means they are trusting that their trainer knows what they are doing. Had you added something to your comment like: "In my experience, I've never heard of that before because I feel that it is very important to "master" the basics before moving on to more intermediate type actions... .and explain why, then your post would have been considered helpful instead of... hurtful.
You have too much knowledge to post a comment like that and not give advice! tsk-tsk... Ok, done with the "mommy lecture". I need some caffeine...
"Be a best friend, tell the truth, and overuse I love you
Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
