Fred, well at least you've been able to make Mark Johnson feel better!
As long as this fiddling acomplishes something.
Its been interesting to watch things change as I moved sub and microphone positions. Peaks and nulls seem to move up and down, and shift in frequency, but the same general pattern appears no matter what. For giggles, I will try measuring at a different vertical location (something other than ear height) next time I fire up REW.
