Who is the author of that incredible analysis? I can't find anything about Volder Z/Derek Vogt. Is it perhaps a pseudonym? Derek Bickerton[1] + Hans Vogt[2]?

His work is building on the observations of commentators Stephen Bax's blog.

This latest video is very interesting, and it seems the translation is progressing

Very nice work
