[CAUT] String Coupling / SB and Bridge stiffness Don M.

[David Love]

I find that when I tune P12ths all the way to the top it's just a bit too
much stretch--except maybe on a concert instrument where I'm aiming for a
bit of an upward curve all the way to the top.  When I tune aurally and
measure that upper octave seems to want to end up somewhere between a
slightly narrow P12th and pretty well stretched 2:1 octave.

Really... I have a hunch that an awful lot of aural tuners have been 
using something very close to a P-12ths stretch for a very long time. I 
keep running into a heavy reliance by many on tests and controls for 
setting octaves that result in either a P-12th in between double 
octaves... or something very very close to it.
