I find this "think mathematically" concept you invoke to be a bit fuzzy. Even geniuses (not me, but I've met some) can be caught out by novel constructions if they haven't had time to consider them carefully. Much mathematical sophistication consists of adding to "the pile of techniques". If a student has too shallow a pile, the goal of educators should be to pile on more. If we suspect the research under discussion represents something real and not simply a series of methodology blunders, then it points to an improvement that educators could make. It's likely that basic dimensional analysis is not a complete answer, but I suspect that an admonition to "think mathematically" is not even wrong.
