Editor’s Choice List also takes into account the company itself not just the ingredients in the food that’s why you won’t find all five star rated foods. The reviews are on the ingredients, protein and fat and how they all measure up in the food. The EC list is for all that plus the company that manufactures the food. For me, 5 star foods are great but I’m also grateful to know which ones are from quality companies with, most especially, quality customer service and their openness as to their ingredients, where they are sourced, etc. Hope this answered your question a little. You can also read, if you haven’t already, under Editor’s Choice Home they have a FAQ section where they will, no doubt, explain it a bit better than I just have.
