My point is that you shouldn't do math to get a first impression whether something is important or marginal. The is a significant amount of people for which math and numbers sound like jibberish and don't perform the elementary proportions you just did. There is even some disagreement about the numbers on this microthread. You have a fair point about the arbitrary landmark though; mine was just a lame attempt at making an example. The key point readers might want to quickly get at a first glance: is this a significant project or a drop in the ocean?
