One of the miss conceptions that people have about the Occupied Point is that they can use it anywhere to pickup points and the setup will not be used in the traverse closure and adjustment calculations.
The occupied point was programmed for 1 case only - it is meant to be a setup on a sideshot, backsighting the original setup on the traverse, to pick up additional sideshots.
If used in this fashion, the occupied point will not be included in any travese closure calculations.
If you use the Occupied Point option to setup on a traverse point that is part of the traverse, then you will have problems with the closure calculations.
In a case like this we recommend that you make a copy of the traverse file - in the original traverse file, delete all of the occupied points and the side shots taken from them. In the copy, delete all of the original setups and leave the occupied points and their sideshots.
Then coordinate the main traverse - do the closure - adjust as you desire.
Then coordinate the traverse file containing the occupied points and its side shots only - this will use the adjusted coordinates as the bases of the occupied point setup and the side shots will be correct based upon the adjusted traverse.
