What's the point of being so exacting about the diet when we don't
know the other side of the equation (the nutritional requirements of
the person in question) to the same level of precision?

Don't get me wrong.  I love a good dietary analysis program as much as
the next person.  It just seems to me that you're looking for more out
of all this than you can get, Jerry.  But good luck! :)
