The Pray Codex offers no “evidence that the shroud may predate the radiocarbon date.” It only dates “to the late 12th to early 13th centuries” and an illustration on it only “shows generic similarities with the Shroud of Turin”. It might well have inspired the shroud’s forgery however.
“The same kind of coloration” is vague to the point of uselessness – many very different things have the same kind of coloration. That is why chemical analysis of the (dis)coloration is far more probative than this laser dog-and-pony show.
The claim has been made that the shroud is “the most studied artifact in human history”.
Given the paucity of rigorous evidence obtained directly from the shroud, this grandiloquent claim is demonstrably false!
Everything else, including Lazzaro’s “elegant” experiment, is mere speculation – and it would seem that it would be more accurate to label the shroud:
The most speculated-about artifact in human history
