Apple Watch Inaccurate & costing me points

<p>I am very dissapointed in the quality of the watch; especially in measuring heart rate during exercise. I have compared the heart rate average on the watch to the Suunto Smart Sensor heart rate stra. In the 59 minute session; there was a difference on average heart rate of 30 beats. </p> <p>Dissapointed that Discovery facilitates the purchase of an product that is inaccurate. </p> <p> </p> <p>I am exercising and achieving my targers but the watch is causing me to loose points; vitality preferred to use he apple watch data rather than the Suunto Smart Sensor data. </p> <p> </p>
