Hi,

wish i had not missed this thread and found it earlier...
I found a diff in one of your previous e-mails, but it's kind of
weird, so i'll simply write how things should look.

Yes, it should be d''.

They are wrong. They should be raised one octave.

Yes, it should. Also the third tapped harmonic should be played on 5th fret.

Yes.

I do.
Concerning the last harmonic: it should be e'' (i.e. note on third
ledger line - remember that guitar is written in \clef "G_8")

Thanks for catching this issue!
