Thank you for pointing this out. So I judged wrongly before when the
roughly squared call counters were missing due to the sometimes
incompletely instrumented Org. Sorry, I correct myself below.

I can confirm: When I re-evaluate, now without elp and by comparing
400.org with 800.org: org-mode and org-version in step #2 of my recipe
are the same, both quadratic. Also "make uncompiled" and "make
compile" are the same, both quadratic.

This means that I can still not get the linear relation expected by
Nicolas Goaziou between the number of elements in an entry and
the processing time.
