Active calorie burn discrepancy between Apple Watch Series 5 and Series 10
I switched from a Series 5 to a Series 10 on 1/11/2025. I work out with both my AppleWatch and my gym's heart rate monitor. Prior to switching to the Series 10, my calorie burn for both my Series 5 and my gym's HR monitor were within 20 calories of one another. I plotted out the data points and, since switching to the Series 10, my watch is indicating as much as a hundred fewer calories than my gym's HR monitor, which still shows a similar calorie burn to my historical stats. Any assistance is appreciated!
