No real dispute here, I'm just speaking from my practical experience 
(having tried "smudging" a unison to hear its effects). There may 
exist a physical basis for what you're describing, Ric. Del would 
know more about it than I would.

I seem to remember from the Weirich SciAm article ("The Coupled 
Motion of Strings" '79?), after the strings on a unison settled into 
the aftersound stage, that if their motion was out-of-phase, the 
bridge would pull them into phase. I somehow also remember that 
slight differences in tuning were also rased by the same coupling 
process. I really should dig out the article before opening my mouth.
