Correct me if I'm wrong but I'm of the impression that flare values are difficult to predict - what the charts always give you is average magnitude. Rocket bodies show a lot of variance in brightness because they're literally tumbling. The 3rd stage, which is the one all the observation programs tell you about, is 3 meters wide and 15 meters long, as well as bright white.

francopoli care to weigh in?
