It tells you plenty. You have made a universal claim that diffraction always causes peak sharpness at the same aperture, regardless of pixel count. While I agree that that is mathematically correct, I also believe that a drop in resolution will in some cases only become noticable at a smaller aperture for a low res sensor thanma large one. That's all I'm claiming. If I can find one instance where numbers demonstrate it, then I am correct.

With no official standard for what diffraction limit means, anyone is free to come up with one that fits the desired result. Some of those definitions will be more useful than others. You and bobn2 have different definitions and will never be able to agree who is right.

For the record, this is the same thing as when people argue over equivalence using different equivalence relation.
