Alan,
I present three animations from Darnell's POV, each with an individual moving eastward across the landing. The first moves the model 1 ft, the second 2 ft, and third 3 ft towards the landing. I hope this is useful for you. I will be happy to refine or modify at your request. I'm not sure I covered all your questions.
My opinion is that yes, a person further back, and somewhat behind Molina, could be superimposed with Molina's reflection. But Molina's reflection is there for sure.

These are super-helpful, James. The time and effort you have put in here, as elsewhere, are greatly appreciated!

Returning to Frazier's reflection, I'm still troubled by the lack of distance between it and his head. On the simulation you posted a few pages back, the greater similarity of head-to-reflection relationship seems to be not with Frazier at edge of landing but with Frazier in deeper shadow from the lintel:

And yet, you seem to have gotten the lintel shadow spot on.
Why the lack of distance between Frazier and his reflection in Darnell? It just seems off to me...
Something to do with blurring perhaps?
