Sounds to me that there should be a rate-of-time factor involved... if you torque it down (hypothetically) with a pneumatic tool, or very slowly with a torque wrench, that the integrity would be compromised between the two extremes of speed due to friction / temperatures affecting the calculations that the manufacturer's used to get their numbers. (Whew!)
Any comments?
Just how exact of a science does this have to be?
