Ok, I'll try to clarify
1) PP's 80/20 means Linda's practicing dressage only 20% of her riding time.
2) the second poster, you refer to "contact" rein both during a discipline (so far, so good) but then, "even when on loose rein, should be on contact" - ? If you mean, that even at rest, after the discipline session's over, the horse should be held on "contact" rein, I disagree. I agree with loose rein as much as possible, for the horse's mouth. I've already posted on other thread that the unnecessary "contact" is incrementally diminishing the horse's mouth, & no one has given me any facts proving it isn't so. (Please back up claims with reasons/facts; why should you be listened to otherwise?)
3) I get uncomfortable around "contact" people anyway, because so often, they're interfering with the horse's movement, rather than helping the horse in hand. I really enjoy seeing a human stay out of the way on a loose rein & let the horse do its job, like in cutting.
