I am using Garmin Connect with a 1st Gen Vivofit and ANT+ Heart Rate Monitor. After i exercise, I see an amount for calories burned on the Calories Dashboard (e.g. 800). However, when i look in the Activities Dashboard, I see a different (lower) calorie burn (e.g. 600) for the same activity. Also, Connect passes the lower calorie burn amount amount to MyFitnessPal. I thought that maybe there was some adjustment for RMR or BMR but that doesnt seem to be correct. Can someone shed light on this please. Thx
