Is that sarcasm again? If not, I've only repeated what you've said. And no matter how well anyone presents these points, in the end these exposure threads are pretty much the only place this sort of thing can be discussed. Over in the Film/paper/chemistry and Enlarging forums when anyone raises these issues they get hammered. It has happened to me many times.
Yes, It's sincere, Michael R 1974. You are really making clear posts that make sense.
