Then he did total screen LxW area divided by cubes/day and came up with 12 sq in per cube of food per day.
IMO that one has stood pretty solid as a rule of thumb.

Yes, pretty solid.
S.M. had to work it out using a practicle method because the fraction of inorganics removed is unknown, so the TTR cannot be calculated.
Practicle testing is best of course because its used to test a theoretical conclusion.
I see now how considering both TTR, and the cube - screen size method, at the same time as though their two seperate issues is wrong, because the TTR is built into the cube - screen size method already.
