We agree, and I also find the evidence dubious at best; I was only trying to explain why the unnamed author of the article posted above might have quoted the "300 years" lapse.
Thanks for the explanation then Sylla It's appreciated, even as I am aware of the details in this case! I was simply trying to highlight the not so correct statement of the writer, but had no time to back it up. My position in the question is more or less the same as Ursus.
