I suggest running a log regression on this data. I can see that it has a diminishing relationship between OPR and scoring rather than a linear one.

It would be most helpful to first clarify what OPR is being plotted and how "actual scoring ability" is being computed.

Unfortunately no one ever posts the estimates' standard errors (which I imagine to be enormous with 10 or so observations.)

In years past, I have posted plots and charts and analyses showing the Ax-b residuals, which is the difference between the actual alliance scores and the "OPR-computed" scores for those same alliances, and makes no assumptions about the error distribution being normal. If this is of general interest, I can generate and post that analysis for 2015.
