One area of limitation I've thought about is the difference in edge type and use vs how the sharpness is measured by the EOU testing equipment. For example, I tend to do more push cutting during use. This comes from breaking down boxes when I worked at a grocery store. For that type of use, high polish and low angle worked well. This is also the way the EOU testers work, by pushing straight down into a medium and seeing how much effort it takes to cut.
However, for those that use more of a slicing motion, and coarser edges, it seems it might not be the most representative test. Don't get me wrong, I've had coarse edges that had very high push cutting sharpness, but it seems it might be like testing a hacksaw by trying to plane a 2 x 4. I've seen some tests used that were for coarse edge slicing ability, but they are not standardized.
