That follows. What you're doing is effectively adding mass to the 
speaking length, requiring more string tension to get the pitch back up. 
This increases the break%. Since the basic problem with these things, 
among others, is a low break% in the low tenor, this makes it less bad.

Let the owner know what you're doing, and maybe after a couple of panic 
service calls, funds will become available to put in some wrapped 
bichords down there.
