Bolts are springs. Torque is used a crude measure of bolt stretch. The intent is to stretch them all the same length. Other less tangible items such as the surface finish of the threads, contamination or oil on the threads, and whether the bolt has been previously torqued have a greater effect on the final bolt stretch than installation torque. That is why bolt stretch is directly measured on high performance applications such as connecting rod caps where possible. It is also why you don't re use flywheel or rod end cap bolts. Arguing over 2% versus 4% is silly. Make sure the threads are clean, or cleaned and oiled for wet torquing. Pick a torque wrench so you are torquing near the middle of the range on the wrench and have at it.
And all of my torque wrenches have gold inlay - that makes them better.
