Here's my results.
As Jim mentioned above, I recently finished doing AF microadjustment on my 1DX (31 lens/extender combinations), 1DIV (20), and 5DII (20). I use the Lens Align Mark II target with LiveView remote shooting controlled by EOS Utility on a notebook computer, connected via USB. It's a completely manual process that probably takes a bit longer to perform than some of the automated processes that are currently available, but I don't mind because I get to see and understand exactly what's going on. Besides, the time for changing setup between different cameras, lenses, and sometimes extenders takes far longer than the time to actually do the AFMA tests.
Of the total 71 tests I performed with three cameras, fourteen lenses, and two extenders, 36 results were 0 (zero), i.e. no AFMA adjustment, and only five individual combinations were outside the range of +/- 2: three were with my 135/2L (-5, -6, and -3), and the other two were with my 100-400L IS with 1.4x III (-3 and -3). None of these "moderate" adjustments between |2| and |6| were on the 1DX, for which the highest adjustment values were +2 and -2, and over half the 1DX conditions were zero.
P.S. Jim, how did you get AFMA values for TS-E lenses?
