But the strange thing is that it already allocated the correct space for parts 
2 and 4. I'm surprised that it behaves differently when I change something in 
a completely different part of the document.

Onc I encased pieces two and four by one bookbart, they fit into two pages 
together. Now, piece 10 stretched out to two pages (3 systems on the first, 
one on the second page, which was the last one of the document).
Then I added a bookpart around piece 10, which made it fit onto a single page 
again. Guess what -- this time it was piece 9 that stretches across two pages.


It’s as if lilypond is trying to keep an even number of pages.

You saw the file, there is no global page-count defined. I’m stumped.:-|
