What about mic placement for listening positions that are outside of my front left and right. I have seating arranged in a horseshoe configuration with a couch facing the center; I can get 3 measurements going down the top of couch (more if I put the tripod on the seat cushions). I have a loveseat to the left and a chair to the right both angled forming the "U" shape but these seats fall outside of the mains on either side. Is it OK to include these seating positions when running YPAO? Audyssey says not to do this but I couldn't find Yamaha's recommendation.
