Larry,

How right you are.  Torquing fasteners with a torque wrench is an endeavor
fraught with inaccuracies; to add breakaway torque to the mix, only makes it
worse.  Torque wrench readings should be taken while on the move, so to
speak.  Even at its best, all that really can be said of a system of
fasteners torqued with the same torque wrench is that the fasteners are
stressed equally, whatever the clamping force may actually be.
