Analyzing the Fed Rate Cut in Mathematica

The Federal Reserve cut the federal funds rate this week for the first time in four years.
And it happens that I am working on a new economics data function for Mathematica--so I wanted to see what typically results after such a reduction in the federal funds rate.
The Fed makes much of its data available on the web through the FRED II database. So, all I had to do was point Mathematica's powerful Import function to the site, and I instantly had the data in Mathematica for analysis. It took one line of code.
A couple of short Mathematica evaluations later, and I had a list of all the previous occasions when this rate fell 0.5% or more. I immediately noticed that these large drops sometimes come in "runs," and decided to focus on the large cuts in each such sequence. I found 15 of these which go back to 1954.
There are obvious natural periods
