NOTATIO

To take things off in a tangent: we need not 'pretend' that engraving is still ... well, engraved. If computer technology lets us create results that were impossible before, then we should consider them. Notation has evolved over the centuries, and there's no reason why it shouldn't continue to do so.

For what it's worth, here's how the latest stable build of LilyPond (2.22.1) does it. Very similar to the Breikopf 1917 sample. I do feel the first beam is a bit to close to the notes compared to the other groups, but not a bad choice as-is.

Yes, indeed. If the computer can finally solve what is clearly a vexing issue, then this would be a worthwhile contribution.

tisimst, the LilyPond beams look thin to me and not quite a 1/2 space in thickness. This has some impact on the angles. I agree about the first group. The stems on the first note is only about 2.75 spaces long.

In all "analog" published examples above (scanned) it seems to me that it is not only difference with the angle, but also the beam width. They all look "more than 1/2" space (obvious for the first, oldest example). Perhaps 0.6 and the spaces between beams are also thinner.
