Why do you trust focus fine-tuning so much?

I haven't tried using lens micro adjustments for focus bracketing, but I wonder if you've done controlled tests to see if the focus increments are indeed evenly-spaced and reliably so? I'd be very surprised if they were either that precise or that consistent.

There's a reason most focus stacking is done by moving the camera or the subject in precise increments. Focus bracketing via an auto focus lens may require more depth of field to provide the necessary detail overlap.
