Pitch, yaw and roll must all be under 0.2, correct those first.
Then translate left/right, up/down until lined up with the docking port. Get errors in line up below 0.2m.

"Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which The Party is always right." - George Orwell, 1984
