You’re not nuts. It’s completely possible for it to run that retarded. That’s how my 7.3 IDIT engine was when I first got it. The white/grey smoke was billowing. IIRC it was 13 degrees retarded a 2000rpm, so 21.5 degrees off. It came from a wrecked truck, so someone was driving it like that. It sounds like you were using and reading the meter correctly. Go ahead and set it where it needs to be.
