## Is this correct?

To me (from a 12-tone perspective), it seems that # and b got mixed up?

The naming of the notes in the diagram is apparently based on stacking fifths - F# is a fifth above B, F is a fifth below C and Bb is a fifth below F. But since the fifth of 16edo is so flat, the result is very different from what would be expected form a 12edo perspective. It is also to be noted that the interval C-E, with the note E 4 fifths above C, actually stands for a MINOR third instead of a major third as a 12edo perspective would suggest.

So you can say the notation IS correct - but maybe the system behind it is not so recommendable for 16edo. This problem has been addressed in the development of sagittal notation as well. Sagitlal notation indeed recommends to notate 16edo with a notation based on the fifth of 48edo instead.

I see, thanks a lot for the explanation :)
