What do you mean?
What clues?
The ones that would exist if Jabba's hypothesis was correct. Jabba is once again starting with his conclusion and ignoring evidence which doesn't fit. Because he does this, he seems to think that that is how all scientists work. As we keep telling him, science doesn't work like that - any 'clue' that was observed would be part of the evidence, the conclusion isn't formed until after the evidence (ALL of it) has been tabulated. Everyone in the thread has pointed this out ad nauseam, but Jabba is not listening.
- But Agatha, I don't think that those who agreed to that were the scientists involved in the actual dating.

If anything, that provides an additional layer of assurance that there were no amazing visible invisible patches, as yet another set of people have observed the samples and noted their observations. You need to understand, Jabba, that the scientists were observing and collecting evidence, not forming a hypothesis. That was done later at the BMRI, after all the evidence was gathered, including the results of the carbon dating processes (two of which, we remind you once again, were done blind at the final stage).
You really are clutching at straws with this patching idea, and the only way such a patch could be worked into your theory (as well as the shroud) is by using techniques which defy naturalistic explanations, or by accusing people with vested interests in dating the shroud to the 1st century of fraud during the chain of custody.
You are positing a patch which is invisible to the naked eye, which matches the weave of the shroud and the invisible linen banding so precisely that not even the most powerful microscopes can detect any irregularity in the weave or banding. Further, you are positing that this patch was put onto the shroud in an area well away from the image by people who failed to record their work on the shroud at all, despite the presence on the shroud of huge and very obvious patches, and despite these amazingly talented people having absolutely no idea which part of the shroud would be sampled, hundreds of years later.
Time for you to explain your theory, Jabba. Here are some questions for you to answer:
1. When did this patching of the shroud occur?
2. Who did the work?
3. How did they do it (remember, the weave and the invisible linen banding shows no sign of patching in that area)?
4. Why did they do it?
5. Why was it not documented?
6. Why did they choose that area?
7. Did they know when, where and how much of the shroud would be sampled for radiocarbon dating purposes?
8. Why, if technology that allows truly invisible patches to be applied to fabric which match both the weave and the linen banding, was this technology not used for the other very obvious patches on the shroud?
Off you go. No invoking of magic, or anything illogical. Unless you can produce a tenable theory which accounts for all of that, including the chain of custody, you are wasting everyone's time and the site's bandwith with your patching idea.
No doubt you'll 'come back to this later' or ignore it, but consider the message you are sending to everybody of the paucity of your argument if you simply avoid the hard questions.
