All the above boils down to - trust - I trust Cybertuner to hear all the
partials (etc that have been listed before) and the forcasted overpull
to tune the note as where it should be, so when you are all done they
are in tune with the rest of the piano.

So bottom line, I - trust - Cybertuner to put the note where it should
be - and - by the testing done by other people, its pretty darn accurate.

As I said - trust - just like you trust your ear to tell you where to
put the note.
