A guitar that does have the intonation set > properly can produce harmonics that are not in tune with fretted notes. I have found that tuning to E works best. Of course I also intonated my guitar to the buzz fieten offsets. So I tune the first string to whatever instrument I need to be in tune with (my piano works good). Then tune B to E at 5, G to E at 9, D to E at 14, A to E at 7, and E to E either at 0 or 12. I think this results in better tuning than the harmonic 5/7 that I used to use.
