We tend to throw around facts and figures to describe the work we do: "We found 11 bugs last week." "That release was 9 months long." "We have 3000 automated tests."
One of the dangerous things about facts is that they have different meanings for different people.
For example, let's say we put 10 man years of work into a product. If I'm a two-man shop, that's a lot of work! If I'm IBM and my project team is 20 people, that's a pretty short project.
So be careful when you're bragging. Your mountain may look like a molehill to the person you're bragging to.
