I mentioned that to him and hopefully he'll start including CS HPI numbers.
What bothers me is not the fact that he's reporting the median price – that's okay. But his conclusion was that prices were rising all the way into 2007 and came crashing down after that. He thinks that prices have been declining for only 11 months. All of the Piggies who have been around a while know that this is untrue. So for an "expert" to come out an make that kind of fundamental error is, for me, a tell-tale sign that he's not to be trusted.
