Hi
1 Currently, AM5 does not support showing how much you moved.
Calibrate Home Position feature is used for those who think their mount is not in the precise home position when the mount finishes the Go Home operation.
2 About the first GoTo object being way off in RA and Dec, is due to all the reasons you mentioned above.
And since we can't sync near to the pole, so we can only do a rough calibration, and after you do a 1-star alignment, the GoTo will be more accurate.
3 Will conveyed your feedback to the team.
