I messed around with Audyssey quite a lot during the short time I had my 805, and without fail it was correct on speaker distance except for my sub, which it would always claim was 30+ feet away. If you do some reading on the Audyssey thread over at AVS, this is common and IIRC Audyssey claims to be by design. Speaker size detection was inaccurate at best. The major issue I had when enabling Audyssey EQ settings was a near non-existent LFE experience. I never could get it to dial in correctly, so I ultimately ended up disabling Audyssey.
How many mic positions did you use for calibration? I always used all eight, however the first pass is the only one where distance/crossover are detected.
