measured values from any one publisher deviated quite a
lot from score to score, sometimes from page to page.
I think that's part of how page turns work out much nicer in
printed manuscripts than by default in LilyPond. I was
complaining to my brother about how difficult it was to work out
page turns in one particular piece of mine, and he pointed out
that I was probably using the same margins for every page.
A priori, I would say that changing margins are **not** a good
idea... but since professional typesetters do it, and I never
noticed myself in 25 years of music-playing, I have to admit that
maybe it's a good idea.
