Calories Burned In Manual Workout vs. GPS Tracked

[LCrads]

Good morning all. I was wondering if anyone had this problem as I can only find very old threads and I'm getting nothing from the live chat. 

I have a Charge 4, last night I tracked a walk I did via GPS so I could see the route afterwards but also recorded it as a exercise without thinking so have both logged.

My question is, both have recorded very very different calories burnt. The GPS one looks correct but the workout/walk which I manually did is very high. Problem is, I record most exercise this way so are all my workouts from the many years of using a Fitbit much higher than they should be!?

Uploaded pictures for reference can be found at the below link and I cannot upload the photos to the Forum!

Any help or guidance appreciated! Weight is monitored by the Aria scale and height is showing as correct so no idea what is throwing this off!

To make sure I understand, are you saying first you recorded the walk using the Exercise App, with GPS turned on, starting and stopping the workout from the tracker itself.  Then afterward, you went back and manually logged the walk for that same time period, inputting required parameters such as start time length, etc ?

I guess I'm not sure what you mean by "recorded it as an exercise" but I think you mean manually logged it as a walk after it was done.  Is that correct?

I would love to know the answer, as I have the opposite happening. Crazy enough I do the 1.5hrs at the same pace you do and get the lower cal burn when I manually add the walking and get the higher version if I start the walking through the tracker with gps.

Not fully understanding what you did, but one thing to be aware of: When you manually log a workout after-the-fact, fitbit ignores all the data it recorded, and goes only by the parameters that you input, ignoring the heart rate data it recorded; as if assuming the reason you manually logged it is because you were not wearing the tracker during the workout so are just trying to get an estimate now.
