I have more problems focusing a faster lens when it is wide open
I'm sorry to say this, but that makes no sense.

Beauty is everywhere when you have the best equipment.
A chimpanzee holding a Phase One Med Format camera is nowhere near as good as a human with any camera, including any point and shoot camera. Beauty is in the eye of the beholder. It is necessary to first "see" beauty in order to be able photograph it.

Your request for a better focus screen has already been addressed by the mirrorless Electronic View Finder (EVF). Twist the lens or press a button and the display zooms 10x into the details. Just skip yesterday's DLSR technology and move straight into the future.
Yes focus zoom is a nice feature, but I still think the old SLR split prisms facilitated faster manual focus and they were spot on.

If a f1.0-f4.0 or larger is a fast lens, depending on focal length, and ...
an f8 or smaller is a slow lens, then ...
is an f4.1-f7.9 simply a half fast lens?

is an f4.1-f7.9 simply a half fast lens?

I'm sure other brands have thus, but the Canon R has a very similar manual focus aid, a graphic in the viewfinder showing 3 triangles, left right and center that converge into two when manual focus is spot on. The Canon RP and also the R has focus peaking, which involves the edges of the subject glowing red as they come into focus. In a way both are better than split screen.

Do current autofocus lenses gain any advantage from faster lenses?Thanks
The advantages of a fast lens are not much different today than they ever were.

Physics is pretty consistent.

I’m not a CANON guy, I’ve owned a N2002, N8008, F4s and D7200 and have Nefertiti’s had fast glass confuse the AF.
I think Nefertiti and I went to different schools together.
