Activity accumulation differences between M430 and other Polar devices
The Polar M430 uses a new calorie calculation algorithm that measures your calories more accurately. Through more accurate calorie calculation, the algorithm also affects the accumulation of daily activity. The calorie calculation is based on an intelligent combination of heart rate and acceleration measurement.
If it seems that your activity goal is too easy to reach, you can change your activity level. The activity goal is based on your personal data and activity level setting, which you can find in the Daily Activity Goal settings in the Flow web service.Choose the activity level that best describes your typical day and activity from three levels. For example, if your current activity level choice is Level 1, you can change it to Level 2. This way you will get a more demanding activity goal.
