The map below, of the specific pattern in the cycle between the cycles mentioned above, may be the odd ball out. Perhaps an interference behavior of a wave? Some science.

Below is a graph of the 500mb numbers for a five day stretch encompassing this comparison of each cycle. The blue and green match up pretty well while the red is slightly different.
