FWIW.... Brings up some points to consider..... Stretch is the best method to get the desired fastener tension BUT the accuracy of the measurements for fasteners of this size becomes the problem..... .005" +/-.001" is a +/- 20% accuracy, plus any errors from angling of the gauge off-axis. Not as consistent as you might think. Torquing has more accuracy/resolution in a good wrench and operator reading it, but then the friction variables come in to effect the results, despite better resolution on the equipment.
If you pick the stretch method, the torque really just becomes a check on whether things are getting way out of whack.
