I know you are the expert

Just saying that proper clamp force (or practically anything) has some acceptable tolerance range, and dry spec can be (should be) developed based on variations from components, friction/ stick-slip, etc. and yet to assure the clamp force in the proper range, instead of hitting the exact number... I do not have a fancy torque wrench with precise load-cell either but assuming some gage error is in the factory equation of the spec.

I do not have factory service manual but the owners manual and Bentley I have handy do not indicate to lube....

And just for reference... 718 manual says NOT to grease (lube) those bolts... I know, different car/ design but.
