MFP's Exercise Calories More Accurate Than You Think?

It took me a while to get to this point, but I'll just skip ahead to the main points to make this a bit more succinct.

I was really ready to just throw out my Fitbit Charge HR because I assumed that the high calorie burn it was giving me was ridiculous. Then I remembered a fitness point that after cardio, your calorie burn can be higher for up to 36 hours. I finally realized that my Fitbit was reflecting this - calories both during and after.

It finally hit me - what if MFP is doing this too?

For example - I have my Activity Level set at Sedentary because I have an office job. For my circuit training class, it gives me 550 calories. My Fitbit shows that during the class I really burn about 350. So, what if that 200 difference isn't really an inflated number. What if it is MFP's way of accounting for the afterburn difference between my cardio and my sedentary setting?

Thoughts?

Everything I've read suggests that afterburn, in terms of calorie consumption, is fairly insignificant. I would not chalk up apparently high calorie estimates to afterburn.

IMO, estimating calorie burns is REALLY difficult to do. Ask 5 people to estimate and you'll get 10 different methods producing 20 different numbers.

IMO, It's an estimate. Treat it as such.
