Yes, I understand that's the makers' explanation. I just don't 
think the explanation makes a lick of sense. How does a piece 
of rubber or felt only damp "certain" partials in a string 
segment less than 10mm long? The bleed through observation was 
my explanation of what I think is actually happening, and did 
make sense, at least to me.
