You are an wrong. Contact is not important in this issue but you are still wrong. Let's assume that you are correct, although it is BECAUSE a patch was sewn into the Shroud to replace the cut out Raes sample, that the 0.2" wide section was cut away... to remove the seam and portions of the patch. The original sample was STILL CUT adjacent to the Raes sample location. You are maintaining that that 2 tenths of an inch was sufficient to divorce the material of the C14 sample from the material of the Raes sample. Absurd.
If that is the case, are you then also maintaining that although the Raes threads are DISTINCTLY DIFFERENT from the Main body of the Shroud, the change over from cotton containing Raes threads to 100% Linen Shroud threads... invisibly... occurred in that small, 2 tenths inch trimmed off area? if so, then you are admitting that the Shroud materials are not homogenous throughout its composition and therefore invalidating the C14 tests.
However, that is irrelevant because the second Arizona sample was taken directly adjacent, without removal of any compromised strips, and completely sharing one side—you see the curved edge?— with the Raes sample. It was the MIDDLE portion that was retained as the control... your so-called "Riggi sample." Here is a photograph with the sample areas drawn in from your own source:
The lower segment, closest to the edge, is the second sample that the Arizona lab was given. Your source comes to the conclusion that:
...the statistical characteristics of the data from each radiocarbon lab appear to indicate that, in the case of the Oxford lab measurements, they were drawn from a statistically different population.
That means that the samples were NOT the same. This conclusion is a confirmation of a previous scientist's work that also concluded that the C14 samples were not statistically similar enough to have come from the same source.
You are an Atheist apologist who cannot understand good science when it hits him in the face.
