summer sharpness in low tenor

[David Love]

As you say, for plain wire.  It's different with a wrapped string.

That's not exactly correct. Change the gage size of a plain 
wire unison in your scaling spreadsheet and watch the tension 
and bp%. The tension will change, but the bp% won't. For a 
given pitch the only way to change bp% is by changing speaking 
length.
