Difficult Part:

I found the most difficult part to be pages 658-660 of Atela et. al. I'm unsure how the quadrilateral Qm,n is defined and what points m,n refer to (arbitrary ones or specific ones). In addition, I was fairly confused by their definition of φ, in relation to S.

Reflective Part:

I find it interesting that, given the relatively simple Hofmeister rule, the paper's authors were able to extrapolate the math involved into something quite complex and byzantine (this, in turn, describes a fairly simple to describe phenomenon).
