I was looking through the lilypond-devel archives trying to find
discussions that  I thought were held on this subject previously, but I
couldn't find them.

I did, however, find this post that indicates that the beam thickness and
the blot diameter interact when determining the angle of the beam as
defined by its centerline:

I found the attached .png to be quite interesting.

Thanks,
