I generally do my hourly step challenge for 9 hours from 7 am to 4 pm. There are times when I have a schedule change and I would go to settings and change it to start at 8am. When I have done this I noticed that it also changes my history to display to the new time and then I don’t have the full credit for the 9-hour challenge that I have earned. Certainly there are times and events that need to be taken into account and allow for an amended start-stop without rewriting and erasing my history.
