Corrected the Accelerometer Calibration page. Had to run it 2 more times to make sure I was right, the sound for when you repeat a position is like a warning - it’s not a big deal - just go to a new position. It would be best to get a routine - the first position you start the test in does not count you will have to come back to it, needs to see a change in position first - I’m guessing. So if you start with it level and battery compartment facing you will have to come back to it.
