10:1 more 'techs' these days own a cordless impact and no torque wrench.

To be fair a lot of torque values assigned in service manuals are not critical values and are based on thread size/pitch and the material it is going into. A lot of values are easy to guess based on looking at the hardware. Experience comes from knowing what is a critical and what is not.
I remember on the YZF series of motor a common failure was guys who didn't know any better would tighten the cam caps without paying any attention. This would score the cam and head, the cam would then seize to the head hard enough to spin the timing sprocket a couple of teeth out of phase
