No problem! I'm notoriously incapable of guessing how much inflation has happened in the last {20, 30, 50} years. I was surprised it was only 1.5x (I had predicted ~2). I agree that CPI is a particularly clumsy measure (not mentioned is the fudge factor in how accounting for stock/option-based compensation has changed). Your comment had the desired (ultimate) effect though: I really haven't been watching how much cash Facebook has been generating, and it's amazing to compare it to Microsoft at peak monopoly.
