I take kickboxing classes and have had issues with the watch stopping an activity because of the pressure on the wrist. I recently began locking the watch and it doesn't appear to be calibrating correctly with the Calorie Burn Total for a ring completion. See below. I have an 800+ calorie burn during my activity, but only 700 total? Both are measuring active calories. I also started doing this after I updated the watch OS so I am not sure if that is the culprit. Thoughts?
