I suppose when somebody decides to document it, or do some extensive testing we'll know for sure.

If you make the 32 inch draw bow a wee bit wider or longer it isn't more strained. The aim on all bows should be to make them feel the correct strain for the wood at full draw. Be that 30# 50# or 150#. Wood doesn't know what bow/design it is in - it just feels the strain upto its limits then fails if we push it past.
A longer draw on the same bow/same arrow makes it more efficient.

That's how it looks to me anyways

Parallel, because they are narrow to start with, and if you go too narrow too quick they can bend sideways. The thickness tapers so the width doesn't need too.
They taper quickly and gracefully at the tip because they can, and it saves weight. I see very few bows that couldn't actually be thinner at the tip. I see plenty where they look like pencils at the end, where the horn nock has been fitted but there has been no attempt to blend that into the limb. Bear in mind you are going from a circular section at the nock to a D section in the limb, if it's not done nicely it looks hideous!
Here's a post that shows what I mean...
