Oh, is it that easy? All I have to do now is print out the models on my 3 dimensional printer at 1:1 scale and dip them in a tank of water and see what the volume is. By this formula it is obvious to see that a metal character, such as the D-Bot, will weigh roughly the same as Victoria. That thought alone is enough to make Victoria go on a crash diet or over-use her skinny morph dial. Seriously now, what I was suggesting is that he uses the standard medical weight to height and build ratio to get a rough approximation of the weight of his character. It's just a rough idea to use in a character profile, he's not looking for exact science here.
