Rex,
I think we are in agreement but if I may add a little more clarification: JMO: When backing off the nut before re-torqueing, one should only back off a minor amount. I only back off until I feel the nut move and then a tad more; way less than 1/8 turn. I would say the typical amount to back off is only about 5-10 degrees.
The objective of backing the nut off is to eliminate the "stiction" (static friction) between the two surfaces. We do not want to significantly reduce the torque the stud and nut are applying to the assembly.

"stiction" I hate that portmanteau. I don't like the word portmanteau much either.

Good Day!
