|I wasn't trying to agree or disagree. Just adding what I thought was a useful comment.|
I've been around cameras for a few years. I still have a working Nikon F bought in 1965. I was a darkroom technician for four college yearbooks and made the final prints for three. I never used a camera with any automatic features for the first ten years I was in the hobby.
I sold darkroom equipment at Altman Camera in Chicago in 1970 and 71. At the time it was the largest camera store in the world.
Your explanation is fine. I learned something from the discussion of t-stops. I just thought it left the impression that the effective f-stop is something to be concerned about, and I doubt that it is.
Since the whole point of f-stops is supposed to be a metric of light transmission that is the same across disparate lenses, the explanation would be incomplete without discussion of how the simple f-stop metric isn't sufficient for that objective. That's still true whether current TTL metering makes deep knowledge of light transmission in optics moot for a segment of photographers.
I gave my last Nikon F to a friend, but I still have an F2 and a Beseler 45MX. I have yearbook photography, photojournalism, studio photography, public relations photography, and event photography in my work background, plus coursework in fine arts photography from U. Florida.
