I vividly recall watching the CT anomaly plot for 2007. Was it going to go over the 3m and off the graph or wasn't it.... In the end it didn't but it was very, very close. Then, after 2008 they re-baselined the whole series and caused much confusion and a less "interesting" seasonal graph set. Well till 2012 that was. If they had not re-baselined it, then 2012 would have dropped right off the bottom of the graph.
