The highest resolution that the assessors could still discern in the sharpest part of the screen(not neccassirily it's center) in the most performing movie theater was about 875 Lines/PH
I could see that, for the "most performing movie theater". I'm not interested in the quality of the "most performing movie theater". That's irrelevant for high quality film restoration. A proper restoration would try to achieve the quality of the highest quality projection, such as in a high end 70mm theater with a brand new print. Do your studies indicate the resolution of high quality 70mm projections of brand new prints?
No those studies do not take into account 70mm projection.
But star wars was not a 70mm production---it was merely blown up to 70mm from it's 35mm source.
And 70mm contact printing will suffer the same degradation through an analogue duplication workflow as 35mm.
According to this member of the Film Tech forum 70mm blow ups from the 1980's are not as good as 35mm prints made within the last 10 years(even if these same 70mm blow ups were better than their 1980's 35mm equivalents)

Still though I have to point out that since most 70mm prints were actually blowups, and of those we're talking mostly 80s, that is the basis of my post. With that being said, lets take a blowup from the 80s. Comparing that to a 35mm print of the same title (from the same printing), the 70mm blows it away. Its not even funny how much better the 70mm is. (If Joe was comparing it, he would probably use an analogy of a high bitrate blu-ray vs. a 3 generation "EP" VHS dub.)
BUT...compare that 70mm print from the 80s against a general release print made at a Technicolor lab (not the crappy Deluxe high speed prints from Canada) over the last 10 years and suddenly the 70mm print isn't so special due to technology advances in printing and filmstocks. I've seen regular release prints over the last decade that are superior visually to the 70mm blowups from the 80s. I can make that statement fairly because I have the capability of side-by-side comparisons today, whereas most of the people on the internet do that comparison based from their memory 20+ years ago, which is not fair nor accurate at all.
We also have to consider what happens when we take an 80s 70mm print and compare it to a recent 35mm re-print of the same title. Its sad but true, the 35mm reprint made within the last several years HAS A SHARPER IMAGE than the 70mm original print! This is no joke. Welcome to reality.
