Don't forget, there rarely is such thing as a persistent '14-'15 type pattern. Many times, our pattern are sort of in between good and garbage. The reasons why sometimes these break right (like Dec 07 for instance) is because of some subtle, but notable distinctions in where features like troughs and ridges are placed.
So it doesn't do a lot of good when you see something not 100% perfect and get all bent out of shape. I don't see anything wrong as a whole on the EPS, especially by December standards. Looking forward to a change.
