One key point to add. For my cge pro the mount knows exactly where it is after it syncs. It is essentially perfect. But it is imperfect in landing where it was told to go.
Despite this goto error the mount is operating fine in terms of its goto specs. It is not specd to perform exactly as sgp wants it to - so it has no obligation to perform the way sgp expects.
Other mounts don't have this goto issue but they do have an issue with sync. It is similar that the mount does not want sgp to use sync like that.
