I don't think that's generally true. It's probably true that all manufacturers 
calibrate their torque wrenches at one value, but the good ones will make an 
effort to make their wrenches linear. None will be perfect, but it's probably 
impossible to predict in advance what imperfections remain.

It's probably true that most makers calibrate their wrenches near the top end 
of their range. What happens below that is probably more random than 

If the choice was mine, I would do the calibration somewhere between 66% 
and 90% of full scale. 75% seems like a nice happy medium.
