That’s very interesting material, Shaun. Thank you for taking your time to do it.

Oh, and to answer your other question…a psychoacoustics presentation with a number of examples can be found here: https://designingsound.org/2014/12/designing-sound-discussion-group-psychoacoustics-for-sound-designers/

It’s rare to actually pan dialog, and for a number of reasons. The convention is to keep dialog in the center channel in both film and television. There are exceptions, of course (the film “Gravity” is an excellent example of that), but the majority of works do not pan critical narrative dialog.

I got a bit confused when you cited that our brains “correct” the dialogue’s panning position. Don’t you pan it slightly to the sides when there are characters standing between, say, the left and centre speakers?
