DA, half of the pad is numb. Holding the hand verticle i.e. like giving the thumbs up signal, the top part of the pad is numb, but the bottom has feeling. Apparently there are two nerves feeding the information into the hand.

Ah, the math is simple, but the reality is complicated.
Yes, twice the width of trigger would make half the pressure... on paper. But of course your finger isn't flat and stiff, and therefore the pressure distribution isn't perfectly even. A bit higher at the center where the bone is, and dropping off toward the edges at the fleshy parts in proportion to the stiffness. I'd imagine it looks a bit like a bell curve, the average of which is the trigger pull weight divided by the contact area (trigger width x finger width). Did you ever take a look at those foot pressure machines at the stores that are trying to sell you $40 insole inserts?
Hmm... finger width varies under load too. All calculations are approximations of reality I guess.

Agreed, we make compromises for simplicity sometimes. Sometimes we want to be as precise as possible, but the calculations almost always become more complex. (Remember our discussion on how to calculate recoil?)
Just to add a little complexity to the human side of it, our sensation of pressure is logrithmic and not linear. And along those lines, there is variability between people as well.

Crap, I was afraid of that.
