So within my family, we have a total fo three watches. 38mm and 42mm Series 3, and a 40mm Series 4. All of them seem to suffer from really inaccurate Exercise Minute tracking, as well as some Move calories being exceptionally low. Under 5.0, my daughter's 38mm S3 would give her Exercise minutes for sitting in class. She would rack up roughly 200 minutes during the average school day despite only about an hour of activity. Updating to 5.0.1 over corrected that issue. Yesterday, on a 9 mile bike ride, she earned less than 20 minutes. Likewise, after the first half hour, I received only 4 minutes despite an average pace of 8 mph and pulling two smaller children and about 100 lbs of tandem bike and trailer. After that, I just switched to Other, so I would get credit for the exercise. My wife was on a hike on Saturday, and similarly only collected a handful of minutes after several miles while using the Hiking workout. She likewise killed the workout and switched to Other. She is using a 40mm S4 running 5.0.1. Monthly Challenges and Competitions are worthless if you can't count on the app to track and credit a workout. Anyone else seeing horrible tracking from the update? I've already sent feedback to Apple.
