I didn’t read it either, I skimmed. But I remember Meade saying that middle tuning thing in a YouTube video I watched teaching about his meters. Who needs a dd1 manual when Meade can tell you via YouTube. A dd1 manual is nice to reference though. I use to like the books in school that had a movie to match so I wouldn’t have to read it lol! Sometimes I would middle tune in on that and just listen to one of them tapes who reads the book for me while I hold the book open and sort of follow along. Lol!
