Looking at the code, the /intent/ is to do what the documentation says.

I find that it fails when it overestimates the height of systems, thus putting
fewer on each page than really fit.  Slurs used to be quite badly overestimated,
but that has gotten better since 2.14

As you say, very simple examples tend to work.  Is there anything you use a
lot in your score that could sometimes force staves further apart, depending
on how the note-spacing comes out ?

Canadians are spelling staff with a 'v' now? Oh no!
We Canadians and USians have to work together to preserve English from the 
innovations of the islanders.
