In a can of Reddi Wip Fat Free, which claims to contain 40 servings at 5 calories each, are there really just 200 calories in the whole can? (In other words, are they allowed to round down the exact serving size and/or number of calories, when the serving size is so tiny?) If not, what's the max number of calories that could actually be in there, and is there any way I can find out that true exact number?
