I guess I just dont get "scanning", To me, scanning a negative involves a light table, loupe, and a negative. At that point, enlargement size is determined, and how much grain visibility is factored in. If graininess is part of the "look" I'm after, then I shoot for max enlargment. If minimal grain is desired, then I limit enlargment to where the grain is almost visable. The process is very subjective, its a matter of personal taste, and what you want to portray.
