I have noticed that some US STAR procedures include (slightly) different number of waypoints, depending on which source material is consulted. Take for example the CAMRN4 STAR and its corresponding description from the legacy files provided by FAA. In the legacy files, the reporting point GAMBY is mentioned between KARRS and CAMRN, whereas in the published information it is omitted.

Is there a reason for this or have I misunderstood something?
