Ah, that's the fact I always forget. Using 2.10.4 on OS X 10.4. Also
tried with similar results on 2.11.x.
Hard to tell if y-extent-estimate is overshooting. In many cases
properly respaced systems have the same margin of error as those that
aren't.
Judge for yourself. Two example pages with annotate-spacing added. The
first is not respaced as expected, the second is. Other pages not
included seem to vary wildly from these lengths.
