In the heyday of Sq. taper, millions upon millions of these were installed and maintained by both pros and amateurs with no serious issues. (Yes, some did work loose, but the numbers are small and consistent with other mechanical issues).

So, maybe younger mechanics that were never properly trained might not know how to properly torque a crank bolt, but the vast majority of mechanics, pro and not, can and do install these reliably time after time.

It's not a question of tools, it's a question of skill, and more important, craftsmanship and care.

BTW- if we continue to foster the ridiculous notion that torque specs have to be looked up for every mundane job, the cost of bicycle repair will increase beyond the reach of most of the public, and we'll be moving to throwaway bicycles.
