Please correct me if I'm wrong.

Yup, that's correct, and why I was agreeing with JLMounce, slightly more than what is recommended by the instructions. I was guess-timating in the .040 range. So more like over by @ .005. (.010 over would be .0475)
The instructions as you see leave a range open between .035-.045, sooo...
