This is the real problem in this industry, in any artistic industry tbh. Injecting your ideals of how anyone should go about learning their craft, with such brazen arrogance and reverence for your experience, aren't the kind of conversations we should be having.
Again, if you want to talk craft, go to a forum post about craft. If you want to provide meaningful conversation, to the point at hand, then chime on in. I for one appreciate these kind of tests. The bulk of my knowledge is in computing. As I transition to film, namely digital film, I've found dynamic range information incredibly useful.
