Hi [name redacted], thank you for providing a way to verify the document. That is really great. As a brief explanation. I was genuinely surprised by the publishing format. This is entirely unrelated to the content of the document. I had not seen google drive as a way to self-publish before. So my intention was not (at least not consciously) to doubt the validity of the claim, but more of a meta-comment. I don‘t know Graveley (and had never heard of him before). I am sorry if you were hurt by him (as you mentioned in another comment).
