Magnified AF Errors of the SAFOX IX than the SAFOX VIII !?

Further to my last test to confirm the significant and consistent Front Focusing of the K-r/SAFOX IX under Yellow Light, I decided to check further about the focusing in/accuracy of the SAFOX IX when compared with the latest SAFOX VIII used in the K-x, side-by-side and head-to-head, at the same time, under identical testing conditions, with the same lens (at the same focal) and at the same
