About 6 months ago I followed David D for about a week, but then dropped him as source because he appears to quite often make it up, and when he's not making it up, he turns whatever it is into a personal opinion rant.I searched and cannot find anything other than that post. Seems like a link would be helpful, but likely it's to a suspect source.
This latest is from somewhat of a thread, and I read the thread and he got pretty darned far off into the weeds with his assertions about machines, and the repair of which he clearly doesn't know a blasted thing about.
