Was the title of this post changed? I can't really understand why this comment is at the top, since "it didn't" and "contracted by 9.5%" seems to refer to some specific complaint about the thesis of the article. It's typical for us in the HN crowd to have a superficial knowledge of a domain and get lost in quibbling about the minutae of how the data is represented, but the thesis of this article is the record decline, and focusing on the use of the annualized metric feels like a tangent.
