That is good to hear, maybe mine will eventually straighten itself out but today was not the day. Jogged 4.3 miles this morning, burned 705 calories (definitely plausible). Walked about 3K steps beyond that so far today, for an additional 2800 calories from those additional steps. So essentially seeing *approximately* 1 KCal/step. I WISH! ;D So I will be submitting tickets daily until I get some acknowledgement of the situation...
Clearly something is wrong here. Ave HR would have been about the same for both days but I got much much higher active calories for less steps??
do the 2800 include your BMR? What did the total burn for the day say?
Now, when I look in MyFitnessPal, they are showing a 'Full Daily Projection' from garminconnect of 4483; interestingly, MFP's guestimation of my total from BMR, run, and steps is 3397, still rather generous I think but much more believable...
I may disable that MFP setting as it doesn't appear to help me that much anyway (I believe it takes a new day before coming into effect). If it is not that then likely something is amiss with GC rather than the FR.
By your walking stride length of about 86cm you are obviously reasonably tall but even the 31/12 burnrate of 70 kcal/km appears high (about mine running that distance at 130bpm). It may be worth checking your profile & activity level https://connect.garmin.com/modern/settings/personal (it wouldn't help explaining the very high day on 1/1). Do you a higher number than expected for the net calorie goal in case it is doing something strange in calculations even outside of activities?
