Hi Jim
Sure, you are absolutely correct! In situations where there is confusion, it is sometimes helpful to switch some numbers around until the problem becomes
evident.
Since the only differences between the various versions of twilight and sunset are simply the altitude (albeit negative), I thought it would be a good idea
for it to be tried.
Best Regards
Brad

I think you were referring to the different definitions of
twilight.
