Correct.

Typical one-third-stop f-number scale. The bolded numbers are the full stops. One stop from f/3.5 would be f/5. Two Stops would be f/7.1. Three stops would be f/10. But for landscapes on sunny days you might want to try f/11 to f/16. Depending on the lens you could also try around f/22 but you might start to lose some sharpness due to diffraction.

1.2, 1.4,1.6, 1.8, 2, 2.2, 2.5, 2.8,3.2, 3.5, 4, 4.5, 5.0, 5.6, 6.3, 7.1, 8, 9, 10, 11, 13, 14, 16, 18, 20, 22, 25, 29, 32

Of zero consequence. Just geek noise.

You do realize that Adams used a LF camera for most of his career - right?

As far as focus stacking goes, if you are shooting digital, it’s not all that hard. If you have a live view capable camera, it’s easy. Then there are the newer cameras that do the focusing for you and the in camera part is simply automated. The rest is software. Now focus stacking Adam’s 8x10, that ain’t easy.

Said the cop as he wrote the ticket.

I've gotten into the habit of stopping at a Stop sign and counting 1-2-3 before I start. The cops here have a tendency to hide and catch cars that do not come to a full stop. My son got a ticket while leaving work at 11:00 PM. The cop who was in hiding said he didn't make a complete stop - in the mall parking lot. I went to court with him, and lots of people were there for the same Stop sign. "To Protect and Serve" Right!

OK, here's an f/32 photograph. I'm sure I can find one take at f/64. It's just this one was easier to locate and I knew it was either of those two stops. If there is any diffraction, it's not visible here, or in the 16x20 print.

You are talking about landscape photography and in that particular area usually small apertures will give you sharpness from foreground to background. I am talking about f11 and f16.
The sweet spot of a lens is not necessarily an acceptable f stop for landscapes. I am sure you do not want to shoot landscapes at f4.5 although f8 could be acceptable depending on your interpretation of the landscape.

Use whichever aperture is required for the desired effect. For landscapes, hyperfocal focusing will be beneficial too.

Depending on the lens, your subject, and your distance from it, it can be more than "geek noise". But I agree that most of the time in most situations it's not really an issue.

Rules of thumb are really meant to be very general guidelines. And your calculations are off. F3.5 to F5 is one stop, F5 to 7.1 is another, and F7.1 to F10 is one more.

However, each lens is different and some peak out at maximum sharpness when stopped 2 stops down from maximum aperture, and others at 3 stops. Some lenses, like super telephotos - are best used wide open, and some actually suffer from closing down the aperture even one stop. The only gain would be in depth of field.

If your lens is a Nikkor AF-S DX 18-55mm f/3.5-5.6G VR, then this review and MTF chart indicates that the best overall aperture for sharpness may be F8, but this must be balanced against your desire for depth of field.

No lens intended for digital crop or full sensor cameras should be used at apertures smaller than F16 - yes, a general rule - but it is based on sharpness limited by diffraction and sensor size (which implies magnification when printing). it's the reason why crop and smaller cameras show negative impacts on sharpness from diffraction at wider openings than full frame and medium format cameras.
