Stem lengths (again)

Thanks, Daniel, for taking the time to look at this and to provide us with a detailed answer. I’m still wondering why it is that five identical bars on one system should have any changes, however tiny, in horizontal spacing. As identical bars, shouldn’t they each take up exactly one fifth of the space of the system?

Yes, I agree that all other things being equal, they should indeed be spaced equally. Unfortunately I don’t think I have access to MTF-Cadence any more so I can’t easily reproduce this for myself with your project to tell you exactly what’s going on.

Well, as I wrote above, if I change the music font but don’t update the engraving settings, the anomalies remain. Here’s a version of the file using Bravura. Now only the second bar has different stem lengths from the others.
