too bad...so was yesterday OK by the end of the day? Were there any days, esp days when you did not have an activity, since getting the watch that looked ok?
I say 'almost believe' since, clearly, 912 KCal still seems extremely generous for 3.89 miles. For me, I would expect something more along the lines of 600 KCal burned if I actually WALKED as an 'ACTIVITY' for 3.9 miles, so just strolling around the hospital yesterday (even if it was 3.9 miles worth of strolling) seems unlikely to have burned 912 calories.
I am having the same issue with MFP and the doubling of calories. I did a 20 mile run today for ~1100 calories, but my total active calories is ~2400 calories which is definitely not right!
what does yours show (steps/calories/distance) in the line for daily steps under the activity tab of the step module in GC as per example attached for the day of that run?
One day it's lower than expected, the next day it's way higher.
