The cube equivalent was developed by Bryan / Santa Monica, basically from what I understand he took 2 of his SM100 scrubbers and put them on a 90g tank and then fed liquid coral food according to his developed cube-equivalent measurement method, and then basically fed the equivalent of about 22 cubes/day for a length of time, then figured that this feeding rate was about the maximum that those 2 scrubbers could handle.

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. There are ways to make a certain size screen more efficient by designing to encourage 3D growth
