i was in a message board regarding the fitness tracker. this was my post

i dont buy it. i dont get my heart rate up or sweat when i walk but i do when i bike.
to go one mile:
walking: 2.0 mph = 30 min = 124 calories
biking : 10mph = 6 min = 37 calories

fine i can understand the mathematics there because i covered that mile much quicker than walking but to go slower on a bike means less sweat and less out of breath etc

for that same mile going half the speed:
biking : 5 mph = 12 min = 74 calories

the slower you go the less umph you put into it the fewer calories you should burn but not according to the tracker, that is the part i don't get.
if i jog that mile i burn less than if i had walked it because i covered it quicker?
so when i go out for a stroll/ pedal with my husband and it takes 2 to 3 times longer because he cant go as fast as i can i am burning more calories????

one more:
if i walk that same mile but i spend 3 hours doing it i will burn 744 calories!?!?!?

does anyone else have issues with how many calories are being burned for various activities? i also dont buy that siting in the boat burns as many calories as biking!

here's another variation. enter your walk or whatever under the search rather than map you route and it says you will burn twice as many calories.
i know i threw a lot of math out there, the brain wants some exercise too! lol!

ok last one: say you enter something for 60 minutes but then remove it the sparkspoints doesn't know that and it continues to add the minutes. i forgot what or when but my finger slipped, i added an extra digit and i got points and minutes for it even though i removed it and reentered it correctly. notice that?
