A casual comment in a single article about it being at coffin corner without offering any proof or anything resembling proof, amounts to nothing. It supports just as much.
I suggest a search for Hazelnuts and PJ's posts on the subject.
The other article linked to offers neither support or opposition. It is merely a subjective description without judgement.
The series of articles is a compilation of guesswork and assumptions mixed with a little fact.
So yes, I did read them all. .
