Sorry, this is a little off topic:
I worry about over tightening with all the torque wrench checking. OK, that's not true, I am just lazy. I wanted to use those plastic arrow things they sell to show if a lug has loosened, but they do not work with deeply recessed lugs like I have. So I removed my pretty wheel covers and travel without them. I torque them once and then use a black and silver Sharpie pin to mark the nut and the wheel with a dot. The silver Sharpie can also be used to erase the black dot on the nut if it changes. I have never seen one move. I don't know much about metal, but I suppose it is possible for the nut to not move and the torque to still decrease, but I am not going to worry about it.
(on edit)
I forgot to add that I implemented this technique after the normal wheel installation cycle which did involve rechecking the torque with a wrench after use.
