focus accuracy vs precision SLR vs mirrorless
Reading a good article about AF microadjustment
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 ?
Go search for "Lensrentals Autofocus Reality" and read every single part.

Also yeah, mirrorless have many advantages there.
