Yes, you're EXACTLY correct. As I stated in an earlier reply "Now the issue becomes which food is most effective?" Which is what I was talking about. In thinking about this in work today, I thought of creating a coefficient ( I would need you smart guys and gals who know more about this to guide me). Then, on the analysis of the food item you could, for example, put a coefficient of 2 in front of the protein, and a (-.5) in front of the fat content. then, the food item with the highest sum values would be the best to feed. Then we need to figure out the cost.
Okay, it's getting late for me....I'm up at 3:30 for a good run, then into work.
Thanks again for your interest and feedback
