My guess is that the ear listens to the dominant coincident partials
whereas the SAT might be listening to a different set of partials. Then,
if there are any inharmonicity differences between the strings of a
unison, the ear will want the fundamentals tuned slightly differently
for a quiet unison.

Makes me think of a model C Steinway with the different speaking lengths
in the lower treble section - for an intentional beat in every unison?
