Just throwing in my two cents:
I have observed friends with the new FitBit Charge HR reaching a step competition goal by swinging their arm back and forth while standing still. I have not observed at any point the Band 2 counting arm swings toward my step count. I don't know, but it seems likely that the Charge HR factors horizontal movement more heavily into step counts than the Band 2 does. This would certainly help explain the discrepancies between step counts.
This could be very well one of the reasons for the difference in counts. There is also a bug that I have found on the Band 2 where there are situations that the Band 2 will not count steps.
