The part you didn't mention is that for most businesses it's better to be over than under in the estimation. I also explain this thought process to the various stake holders. We can certainly try to tighten up an estimate, but that runs a higher risk of being under which is usually a worse outcome (promised launch dates are missed, marketing is missed/happening, customers are told, etc...).
