Electrical Competency, what is it?

But for competence we need someone who knows the art of the possible and can pick up someone else's design and make sense of it, even if they have not done anything exactly that way themselves. 

That is a greater skill than rote learning - inspection of an existing thing that is not fully recorded is perhaps closer to fault finding in that sense, and I'd agree that on its own, an ability to follow the OSG as a recipe process is simply not enough.  

Just because that cable arrangement is not one shown in the books,  how to check if it will be fine, and an ability to interpolate current ratings for odd grouping factors,  and to consider non-linear radials and so forth a huge advantage…

The ability to at least in principle author an equally valid alternative to sections of  the OSG, maybe enough.
