Firstly it makes perfect sense when installing a firmware update that makes changes to the AF system to make sure the calibration of the lenses is still correct. As it happened they were not.
"opportunity to bias my tests? Are you suggesting I'm deliberately posting tests to show a problem when there isn't one?
And what do yo mean by 'a little knowledge' ? Seems an uncalled for assumption on the level of my knowledge there don't yo think?
Hmmm??
I think you might be reading too much into what he's saying. The thing is, it's actually hard to directly compare 1.02 to 1.03 because of this recalibration step in between. One thing to do would be to not recalibrate and see what happens. Of course recalibrating kindof makes sense, but it's another place for error to creep in. Was the calibration perfect before? Is it perfect now? I think these different possibilities are what he means by "opportunities to bias." Biases are not all intentional.
I think the "little knowledge" comment may just be another reference to the whole issue of unintentional biases. Lots of scientific experiments go awry even when the people performing them are quite smart.
Nevertheless, it kinda seems to me like your k5 is not working properly.
