I assume that the penis volume is always the same (since we are not removing anything).
Even if there is uneven compression in the vagina and some areas get reduced, other areas will get bigger (same mechanism as clamping..).
I think a lot your post seems to come from the idea of clamping, but clamping is designed to block off valves at the base of the cock, where as sex does not seem to. I can’t seem to find my other fabric measuring tape so I cant test your theory out right now.
An easy way to look at this is to grab your 80% erection and place your hand around it with the same pressure it takes to squeeze an orange. How much can you squeeze down? Now try to do that with a 100% erection. You should be able to squeeze less. So you’re harder.
To look at the above in terms of blood, it would be dependent on how much pressure you can build up. The same kind of pressure you fill up a balloon with, if you take the same amount of pressure and decrease it’s area, it’s going to push back more. What we’re (or I guess “I’m”) looking for is the point it pushes back that you can’t push back (by strangling it with tape, so to speak). You know, Psi, pound per square inch, hmm…

Diagram.
If you had a diaphragm (shown in the middle of the two arrows), it would move back and forth until the pressure’s equalized and there was an equal amount of push.

I think I’m rambling. I hope you get the idea though.
