Tricky as it depends on what load you use. Same load every time, not such a
problem.
I've found that if i have the tip just in the beans to start then it is some
down after they expand so you end up with a moving target, granted just a
couple of steps.
Right now I have a bare tip tc threaded across the top of the metal portion
of the popper and back on itself so the the bare tip sits in the center of
the throat. Don't know if it's optimum but works for me.

Optimum from what point of view?

I put mine in the centre of the chamber, approaching vertically from
above, with the tip slightly (about 5 or 6mm) clear of the bottom. I
decided this was the optimum compromise with regards not impeding bean
circulation (which is round and round plus up the outside and down the
middle).

It works. I find P is sufficient control for roasting - I don't I or
D.
