I tried to make an automated definition (first attachment) and to integrate
it in the grow-beam-var-definition (second attachment). This feature will
only work with kneed beams and if the directions of the first and last stem
are different.
But I noticed a strange behaviour: I retrieve wrong output if the
global-staff-size is changed, or with other changes. Can you confirm this?
Perhaps it is similiar to my problem with your
center-grob-between-definition.
Or am I missing something or doing something wrong or ...?

Looks great and works fine!

Completely !

That's true, but I thought about integrating some features in grow-beam-var,
only to be activated with negative numbers. P.e. the possibility of turning
the peak in special cases. (But I'm not convinced of it. I think I'll
eliminate it.)

So do I.
