And besides, even if you report the raw data like a sane person, people do need to know which calculations to do after they've got all the data, right? There are some local calculations that do tesselate together neatly to global calculations, and you might as well summarize those when they exist. Which requires you to know how to set up the kind of calculation that modularizes well, and distinguish it from calculations that don't.
