<p>I believe the phrase that Xiggi used was “circular” in describing how the PA results are influenced by the raw data, and then the raw data catches up to the PA. Your justification, which you have just repeated, is that it “stabilizes” the ratings. In other words, it acts as an extremely conservative lagging indicator. I mean, we make these impassioned pleas for more accurate, up to date information, more transparency. Then, add the biggest lagging indicator out there? Does that even make sense?</p>
