Can anyone tell me the reason for backing off the centrelock nut by 1/6th of a turn once you reach the correct torque , then you re-tighten again . Torque loosen the torque again seems strange when you think how tight the nut has to be torqued up.

I cannot think of an engineering reason possibly a double check, after all it will keep the wheel where it should be. :?:
I torque the nut up to 600nm as per the latest Porsche instructions , mark the wheel where the iine on the nut is and back it off to the second line then re- tighten . The torque wrench clicks bang on the first mark I made so it seems to be a waste of time and a pain when you use a torque multiplier like I do.
I will follow the Porsche instruction but would like to understand why.
