i'm afraid to post in this thread, but if i follow the logic of this gang bang corrrectly, shouldn't you be adding 16.75 to 56? I mean you're trying to quantify the displacement from the center line, right?
i've literally never measured chainline so i don't know. I just eyeball it and move the hub, space the BB, or whatever's easiest/possible.
