I think this debate better start at noon on Saturday, not in the evening, as it is going to be a long one !
The challenge is that there are very few provable and inarguable facts other than: 15-20 have turned up in various conditions, with two types of chain, and that signatures do vary in detail and placement.
Beyond that, it is all a matter of opinions and these can (and will) be argued several ways in exhaustive detail without conclusion.
