Yes, but it is an entirely accurate parameter to evaluate the HVS (human visual system) as long as the test methodology is not flawed…and editorial review by peers, of either journal article, has found none.

Unlike flawed ‘objective’ measurement which is touted as accurate, like, for instance, that used as a basis for this tech journalist’s *insight*….http://reviews.cnet.com/8301-33199_7...vs-are-stupid/

namely… “but the average person with 20/20 vision can resolve 1 arcminute”,

ergo..“One arcminute of resolution is a best-case scenario."

lah-dee-dah-dee- dah with the math exercise from there.

Which, b.t.w., forms the basis of this chart which is touted on internet forums as a Commandment, rather than just a rough guideline for 4K viewing… http://carltonbale.com/1080p-does-matter/

When the fact of the matter is that this basic ‘objective’ measurement (one arcminute of resolution) is incorrect/limiting in its applicability to real world viewing because other than “resolution”, professional imaging scientists know and hold valid that there are other types of visual acuity which also play an important role in human vision, namely ‘recognition’, ‘detection’ and ‘hyperacuity’.

I don’t have time right now to elaborate further but, perhaps I’ll save that for another post on a rainy day.
