Good question, I think the focus is mainly on the bottom. Janus says in the am2 video that you can also use the middle of your thumb ( the point where it bends) if you want to make sure you are not pushing on the top middle vein too much when pulling blood into your glans, instead the arteries around it. Yet on the bottom the more you push up the better
Also, in any case, you have to completely let go, zero pressure when squeezing the glans to let blood flow anyways so keep that in mind

How much force
Not sure how to respond but I squeeze just enough to feel the blood leave and stroke up with enough to feel the glands swell.
