OK but do they need to do it at run time. What would be the point of design then?

But then, following this logic and the 8 item weigth example, the system would then require the information that the sum is relevant only up to 8 items to be available to people for them to make *educated* guesses. Don't you think that makes things more complicated? Most people I know would tell you, you did a poor design job and that they don't need this irrelevant information.
