However, if your lens was in calibration before you changed the flange, then if it is in focus ( at any place) after changing the flange, no further testing is required. As I said at first, if your lens is out of calibration to begin with, you need a calibration done on the lens. Why not change the flange before sending the lens in, and get that advantage as well.... Of course, it is a cost issue... $250 or so with flange at Leica or $100 plus $20 flange at DAG. Same end result.

There is no issue of being able to change the flange yourself or if all 6 screws are absolutely required (they are not), it's just that if you change the flange yourself the only way you have of checking if the focus is still correct is to shoot, and this requires a lot of careful testing at different distances and apertures, and if there is a problem it is well beyond the capability of most people to fix it themselves.
