That is what I use them for really just as a guide... just completely baffled why the changes...
Looks like they've changed how they estimate calories on the device if you use an HR meter and are tracking intensity.That is what I use them for really just as a guide... just completely baffled why the changes...
Wait, so they are using kJ and kcal as different measures? kJ to report on the expended energy at the crank and kcal to report energy metabolised by the rider? When in truth they are simply imperial and metric units of the same thing.
Am I missing a cycling thing - is this a normal definition of kJ and kcal, or is this just Strava not understanding the difference between metric and imperial units? They have form here - you can't, for example, have miles and °C together - as far as they are concerned you are either American (miles, °F, lbs) or foreign (km, °C, kg).
This is the reply from Wahoo..
"Hi Stuart
We recently made 2 changes to the calculation of calories. Historically we have always used heart rate data to calculate calories regardless of whether a power meter has been paired to the head unit, as a result, there were often differences between the Calorie recording and the Kilojules [Kj] recorded. However, now, we will always calculate this based on power data if it is available. The reason for this change is to improve the accuracy of this data point.......
