Calorie Reading: Fitness Tracker vs Machine

sweatin4160

I recently got a fitness tracker and decided to test it to examine how many calories do I burn during my regular 60 min spinning class.

I normally get a reading somewhere in between 380-450 during each class and during my last workout with the tracker, the machine displayed 435. I was keen to see how close that number was compared to the reading from my tracker and it calculated calories burnt to be 763.

I understand that tracker uses my age, weight, height, etc to calculate that number while my bike at my local gym does not have that information during calculation. But, those two numbers are not even close and makes me wonder if my tracker is giving me WAY for credit than I deserve or if I have been low-balled by the machine.

I can't decide which displayed number will be closest to the real optimal number (which I don't have means to calculate).

Any suggestions or comments?

How did the bike at the gym come up with that number? Was it guess work, or was it equipped with a power meter?

None of those data are relevant to the calorie estimation in this case.

It has power meter.

If it has a power meter, it's not more than 5% off from god's honest truth.
