I studied all of that 40 years ago. The point that I was making is that the yield strength of the bolts can be different. If they are all torqued to yield, then the bolt tensile forces can be quite different as a result.
That one bolt that felt soft also did not exhibit the expected linear increase of torque with angular displacement. It seems to have reached a plateau.
I had one bolt like that in the 1970's on a Volvo engine. I was not really recognizing what was going on. By the time that I yanked the bolt out there was a tell take necking to see. So I got a bolt from a doner engine and put that in and all was fine. That bold simply would not develop torque and the torque stopped increasing as it was tightened.
