Thank you John Jones, Aepervius, Slowvehicle and the rest of you for patiently providing me with a crash course of sindonology so I can somewhat catch up with years of discussion here arriving to the inevitable conclusion the shroud is a forgery. I can see now that there's sort of law that says that the lengths the advocates of a wacky notion are willing to go distorting science and logic to sustain their beliefs are directly proportional to the preposterousness of their advocacies. In the case of the shroud they seem to have monopolized the appeal to authority: you have to believe certain myths because the religious authority says to you "it's the truth", you have to believe the shroud is or may be authentic because a group of "scientist" say yo to do so. And they are allowed to do and say anything to that effect, because for starters that's why they were invested as authorities. So, in the jabba-way, it all boils down to a duel like those in the Japanese painted-cardboard TV-series with a good samurai-like robot and a bad samurai-like robot struggling with force rays that emerge from their robotic hands for the strongest to win.
It's safe to say the shroud is a fake but any utter re-confirmation of that will have to wait because there's no interest in the truth. The shroud is like the Tower of Pisa which attractive comes because it leans, leans but it will never fall. Any attempt to stabilize the tower causes the international tourism to lost interest and $$$$ start to shrink. In a similar way a debunked shroud means nobody will be longer interested in it and they probably flock to what might be the blood of Saint Gennaro which still is surrounded by a veal of mystic mystery.
