I have gone through all six pages of posts in this thread. In the middle of this thread there is some comment about the park and unpack state at first boot up. I have come across an PDF from astrophysics which states that for firmware version S and before, the mount will immediately begin tracking upon start up, whereas after that version the mount will not track until it is told to do so. It also states that when you just turn off the mount without parking first the mount will store its current position and on power up resume from the same position. I wonder if this explains some of the confusion mentioned in those posts...
