I guess neither of us will ever know for sure which is more damaging. I just know that both practices lead to over torqued lug nuts or bolts.
I can tell you that stretch bolts, like head bolts & flywheel bolts can be easily damaged by over torquing. Also, you can measure their length to determine of they can be re-used. Too long & you toss them, not because of the length but because the steel is fatigued and no longer works like a spring when the bolt is torqued.
