What I think is happening here is that there is SO much resistance when the threads are being cut, that the operator gets to a hard point BUT that hard point is not QUITE at the FREEZE point.

It's true that you need to get the feel for when the screws are snug but not over-tightened. After I'd done my very first LO plate swap I got the idea for the rest of my life.  I think that an essential part of the procedure is to tighten the screws progressively. They can even squeal a bit as they're cutting the thread, which is a good sign, not a bad sign. Tightening one screw fully before the others are properly bedding down not only risks distortion but also prevents you from getting the right feel for when the job's done, snugged down but not jammed down.  Round and round you go, always checking that everything's in line, including the covers at the end of the job.  Good idea to have a good look at the harp close up before each part of the dismantling so that you know where everything goes back.
