This is more or less what I was speculating in the original multi-page thread on V-bracing:

"Well, I'm saying it could be actually be intonation in regards to how the notes coming out of the guitar are closer to the harmonic series produced by the strings. In other words, perhaps on a certain fret higher up on the fretboard, the string produces a fundamental frequency of 440 Hz (an A). But, after the note is coupled to the guitar, it might shift it to 440.5 Hz or something similar. I don't know if that's the case, but it could happen."
