Excellent.  Good experiment.

I haven't had a chance to look it over in detail, and I may not be able to for a
while.

But what i would suggest is to model what you think it ought to be with
cylinders, cones, tori, whatever lets you "draw" the result without interfering
with the scene - and then see how it compares.

If you put all of those objects into a union with "no_shadow", that will help a
lot.
