I would like to ask a question or for opinions concerning how far can a caller go in "coaching" during a scored flight. Should rudder inputs/ corrections be discussed? Is it appropriate for "any" coaching to be going on? My feelings are that under contest circumstances that the caller should only be there to call the maneuvers and no coaching should be the rule. I can see an argument at the Sportsman level that some corrections would not be too harmful but then again an even playing field would be harder to obtain.
