They key is good calibration. Most aren’t calibrated and generally neglected.
The other thing is extreme ends of the range tend to be inaccurate and often you need two if you’re going to cover small torques and large.
Smallest torques under 10, personally I’d go on hand judgment. Rely on a torque wrench and (as I found) snapped bolts is easy. Low torque bolts, high spec from manufacturer for good measure and chuck in Loctite to throw it off and you over torque, snap, and then you’re drilling out bolts (as I said, personal experience).
High torques the wrenches are more useful. Particularly with cassettes, cranks, BBs and the like, as a lot under torque them and then wonder why they fall apart.
