Just using Recent Months
Now, when I shared the preliminary version of this research with Bryan Alvarez on the Live 1/27 WO Call-In show, he challenged me to only look at the 2013 results from SummerSlam onwards. Unfortunately, this drastically reduces our dataset, but here's the sketchy outline of what that would suggest:
August - October 2013

With a larger dataset, I would feel more confident about drawing conclusions from this last part. Right now, I'll leave that as an exercise to the reader, so they can twist it to prove whatever point best fits their narrative.
