Since recently I noticed the Garmin 530 records a higher amount of burned calories than I actually do. Weird thing is that when I go to Garmin Connect and see the summary of my day, the number of calories burned is correct, but when I open my workout the number if calories is significantly higher (usually about 10%).
For example, I did a 1,5hr ride yesterday averaging 213W. The edge says I burned 1304cal (and 1183kJ), and Connect says on its overview page that it's 1184cal. I know you can use the calculation of 213Wx 1,5hr x 3,6 to get the number of calories, so in this case the 1184 looks to be right. When I did a 4hr ride last weekend, the number of calories differed about 250cal.
What is going on here? To me it looks like something's not right in the Garmin 530's recording/calculation and Garmin Connect has it right. Thing is tho, the 530 stats are sent to my trainer, Strava etc...
