You seem to be mixing terms and describing sharpness but calling it resolution.  Resolution only describes how much detail a camera/lens is capable of capturing — and not necessarily the quality of the detail that is captured. The problem, in these types of discussions, is that folks keep mixing related terms an using them to describe inaccurately a concept

Your understanding of resolution that purely based on the amount of pixels is very wrong. I know on your logic 41mp Nokia 808 has double "resolution" than 21mp 5D2. The only problem is that when you see such 41mp photos from Nokia 808, you hardly can figure out much detail, or maybe your eyes are different from all others?

DXOMark correctly test the real resolution (P-MPix) that in my words “Fine Detail” that human eyes can resolve that only matters.  Otherwise your paper resolution is just an Utopia that you can feel but you really cannot see

It's not regular sharpness or acutance on your understanding because latter supposedly can be enhanced in software processing. However the fine details only can obtained thru sensor-lens system captured.

Once again you have interjected unrelated terms. Not being able to understand the difference between the term "resolution" and other concepts/terms is the source of your misconceptions. A common theme. You simply can not define or conceptualize the term "resolution" . A barrier too communication you may never be able to overcome.

Terms are not really that important in this discussion. I just want to point out that your interpretation and understanding of DXOMark P-MPix test is very wrong. DXOMark uses terms sharpness and resolution interchangeably but they are not regular sharpness/acutance that you could enhance in LR for example. It's the resolution that human eyes can actually resolve that makes very sense.

I know I keep using Nokia 808 as an example and you don't want to address but that's exact the case to show your understanding is wrong. There is simply no such sensor resolution but only a system (sensor+lens) resolution  that is actual fine detail that system can resolve and present to human eyes can actually see.
