    It is hard to know. My iFit trainer informs me I burned off 600 cals after a 65 mins home bike ride doing HIIT, a pretty hard exercise-sweating like a pig. But than I do a real 25 mile ride on my road bike in 75 mins and mapmyride informs me I burned 1500 cals. In actual reality the shorter HIIT exercise was more demanding yet burned off apparently less cals, like almost three times less. So one of them has to be wrong. TBH I gave up trying to figure out how much cals I really burn during exercises. It is said to lose a pound of fat a week you need to be in 500 cals calorie deficit a day so that is how I calculate, but even then fat loss doesn't necessarily mean one didn't lose muscle mass as well I am guessing. I dont use a fitness watch I am curious myself how accurate they are.

    Who knows. Some trackers are good for some people, but don't work at all for others. It also depends on what you do. Say you do some interval workouts: your heartrate shoots up and the tracker gives you crazy burns. The interval ends after 30 seconds, but your heartrate still remains elevated for a while. Yet you just sit around, hence no crazy burns. Most trackers will still give you crazy burns, which aren't there. That's why only steady state exercise is really suitable for heartrate driven devices. (there seem to be some new developments, but not sure). If you're not that fit then this effect will be even more exaggerated as your heartrate will get higher and remain high for longer.

    You haven't said what you were doing in that 50 minutes or what your fitness level is.

    Is it giving you a net calorie estimate (just the additional calories burn due to your exercise) or a gross calorie estimate (including the baseline calories you would have burned whether your exercised or not)?

    It's within the realms of possible but the range of possible is extremely wide.
    Cycling at a 213 watt average would give you a net cal burn in that ballpark and that's not exceptional for a larger 30 YO male.
