smrobs: no it hasn't.
What has been explained is what to do if the horse gives a wrong response, and how to fix a broken aspect of a particular maneouver.

Muppetgirl: i'm happy to leave it at that if you'd like. But I will respond to those quotes with some more quotes
"Almost every major systematic error which has deluded men for thousands of years relied on practical experience. Horoscopes, incantations, oracles, magic, witchcraft, the cures of witch doctors and of medical practitioners before the advent of modern medicine, were all firmly established through the centuries in the eyes of the public by their supposed practical successes. The scientific method was devised precisely for the purpose of elucidating the nature of things under more carefully controlled conditions and by more rigorous criteria than are present in the situations created by practical problems" - michael polanyi
"In order that the facts obtained by observation and experiment may be capable of being used in furtherance of our exact and solid knowledge, they must be apprehended and analysed according to some Conceptions which, applied for this purpose, give distinct and definite results, such as can be steadily taken hold of and reasoned from." - william whewell
Golden horse: if a reiner "gets it", he won't need reminding of it. Because "getting it" implies they have "got it". And if they have "got it" they wouldn't need reminding.
