Probably the simplest way to double-check them is to set the stringTunings
property to the specified ukulele tuning, then have an automatic fretboard
be calculated from a chord containing the open-string pitches.

Oooh -- now that I think about it that won't work right now, because the
automatic fretboard calculator requires sorted string pitches (i.e. pitch
continually increases or decreases from one string to the next, and ukuleles
don't do that).

So for right now, let's put them in at what is your best guess.  If they're
wrong, it won't hurt anybody right now.  If they're right, we've got it
done.

BTW, I checked your numbers, and they looked right to me.

Thanks,
