So you're sticking with the "There's no advice for new DMs in the DMG?" Because I've shown repeatedly that there is. You have yet to actually address how, specifically, that advice should be handled differently.
The DMG is not a tutorial book and it is quite clear on that, both on the cover of the book and in the introduction. It does, however, offer plenty of advice for new DMs. I would say the majority of the book is advice for new DMs, about all an experienced DM needs from the book is the section on treasure.
