This has been explained several times. Perception != Angle. You only need to "choose" one perception, such as CTEL/A, for the entire range of shots. Every CB/OB arrangement presents a unique perception which results in a unique orientation, even though on the surface the execution is simply CTEL/A. You can only realize this at the table, obviously explanation by words will never be enough.
Hi Monty,
I can't get into it with you here. I simply put out food for thought for anyone inclined to do any critical thinking from an unbiased objective perspective.
That said, I would simply ask you one question though.
WHAT is it... that is objective... that tells you... what is the proper perception for the shot?
Please just think about that?
Best Wishes to You & All.
