Great stuff! This is a nice demonstration of the variability of inflation and how under-trend we have been for many years. There was a strong push from some monetary policy people to move toward a longer term, average inflation targeting that would make the Fed have symmetric reaction functions to upside and downside inflation while attempting to keep a longer term average as the goal. One interesting explanation for high inflation during the 1970s to early 1980s was that the monetary system and supply of real assets had to adjust to a massive influx of working age adults (babyboomers). A second wave from that population event started to enter the workforce over the last ten years. It might be interesting to normalize the data here against the size of the workforce.
