Ambitus engravings are for expressing physical limits.  I can't think of
a tuning/instrument where enharmonic relations could make a difference.

No.  The ambitus should definitely orient itself with its key signature:
it makes no sense using accidentals when a natural pitch is there.

Hi,

the ambitus engraver seemingly picks the first maximum/minimum in the
note sequence and stays with it even when the same absolute pitch comes
up later with a better match to the ambitus engraver's key signature.

Here is a real world example where the ambitus engraver (which is
working in C major) picks c flat rather than b as its lowest span.
Ugly.


Not that I use ambituses, but surely, where there multiple notes of the 
same pitch (I hate to say "absolute pitch", because to take the above 
example c-flat and b-natural are NOT the same pitch except on the 
piano), it makes sense to take the lowest (or highest, as appropriate) 
note - b over c.


Cheers,
Wol
