Reading a good article about AF microadjustment
https://www.the-digital-picture.com/Phot...-tips.aspx
I came through the concept of focus accuracy vs precision he states "The terms accuracy and precision are sometimes (improperly) used interchangeably - accuracy is 'closeness to true' whereas precision is repeatability."
they posted this explanatory diagram

which explains why besides good AFMA I still have few missed shots
my guess is precision is a particular body/lens specific thing and not system related, or does mirrorless have any advantage here ?
