as per above, the spring can be stretched when under tension for a long time - the click types depend on a spring -- and the spring constant - for their accuracy

PS - I am going to ask Porsche AG to pass a law that you cannot own one of their cars unless you pass Freshman physics...

Seriously, I recommend this even to the old geezers out there -- it is amazing how much you can explain with a background in how reality works...

Torque is not a super accurate way to set the tension on a bolt in the first place.
re order of magnitude - that is 10x (!) and I could agree with that if the fastener is pretty far out of whack (a technical physics term) but we had a demo of click type wrenches on a tester -- many were far from accurate.

Anyway, y'all pays yore money and youse takes you're choice...
