Though I worked with guys who would keep that success rate very low?

 I worked with one guy who's method was tighten until it breaks and
back it off 1/8th of a turn. He could snap a 1 1/2 inch grade 8 bolt.
(with a torque multiplier and  johnson bar, but still!!!) The torque
spec was something like 3600 ft lb so he had to be putting over 4000
ft lb to them - - - - -
