I find 95% of folks misuse a round pen, whether under the guise of "exercising" or teaching conditioned responses, an example being the lesser of two evils is to turn, face the human, and be caught rather than made to run; which is a bullying tactic. The problem with teaching conditioned responses and patterns is the day you change the routine, the horse does not know how to react because his responses have been obedient versus thoughtful. Sometimes, this creates him throwing a tantrum or seemingly becoming a fire breathing dragon instead of the horse you're used to.
