Since the CDI is calibrated in degrees, distance in nm isn't relevant unless you also talk about distance from the station. Assuming 1° of accuracy, that 1 nm accuracy would take place at 60 nm from the station. That one of the reasons the CDI reading for GPS and VOR are so different. CDI deviation for GPS translates directly to degrees. 120 miles from a station/VOR waypoint, a very small CDI deviation in the VOR setting can translate to a very large one if you switch the CDI to GPS mode, even if both systems are dead on.
