Hi Andrew
The term statistically significant was not proper on my part and @Dan_Eastwood helped educate me on this.
The evidence I think is significant is:given the blood type was experimentally determined to be AB was on both famous relics:
The relics were mentioned in the Gospels especially John.
Both relics have the same blood type based on current documented experimental evidence.
This finding is low probability (probability of a mammal w AB blood) if one claims one of the relics was forged. If one claims both of the relics were forged this becomes extreme low probability.(probability of both forged relics = P(shroud forged) X P(sudarium forged)).
