Which is, of course, wrong. More torque *available* to untighten than
to tighten. I allways use a bigger wrench to loosen pipes than tighten
them.
Enough opinion. Try it on a torque meter and let us know what you find.
The human factors folks have already done the work.
According to "Human Engineering Guide to Equipment Design",
a right handed person can exert considerably more torque
(about 30%) in the CCW direction.
