I have typed it a few times before: the idea that the flange distance needs to be exact for AF to be on point is just plain wrong. So shims or no shims, it does not matter. What does matter? The lens making the final step less precise than the camera and user would want.
Or: some colour focussing at a different plane than others, a colour that the camera's AF sensor is sensitive to. This makes the camera see things in focus, when the user does not in the final image.
Dave, I feel reluctant to ask you a question since you rarely answer on point when I do. But I will make myself ask it anyway: Do you perhaps use different light sources for the close up situations and the further away situations?
