@Gordon - appreciate its not going to be perfect (2% error over 1 km would be excellent, 5% would be good.). But its definitely still counting 1000s of steps over the course of a day when steps are not there. Today I have apparantly done 3671 steps but all I have done is been up and down stairs maybe 4 times and the rest of the time sat at a desk. I would expect maybe 250 or 300 steps max for such activity.
Its quite easy to reproduce the issue. Just sit look at the watch then twist your wrist through 90 degrees and back varying the speed at which you turn the wrist. The twist used to turn the LCD on should not cause steps.
Will send you another accel log of me doing this, maybe another tuning session will get this to be filtered out.
