Don't seem to be sufficient for what?  It works
perfectly for what it does.  It would be nice to use
both otions you've tried from one point to the 5 here. 
If you're trying to simulate trees or something, just
normalize the angles as straight "up" (toward the SUN)-
and maybe randomize the angle a little bit from there-
that's how they seem grow, they don't concern
themselves with the angle of the surface, just the
angle of the sun.

Exam or macro... which is really more important!?

Why bother?  I'm not interesting.
But... maybe "Ballet pour ma fille" will be.
