Calories burnt: Hub vs Garmin
I see a not insignificant discrepancy of total of calories burnt between these two.
I am using a powermeter for the Garmin, and then the Hub/Zwift calculates it's own number using it's internal meter.
Last training ride I did had 1260 on the Garmin, and 980 on Zwift. The average power from the Hub was slightly higher than what was recorded from my powermeter. I use HR as well.
Ideas on which one to follow? 300 calories is a pretty significant amount to account for. Rider and bike weight are set the same in both Garmin and Zwift.
