I am a heart patient as are many others who wear your watches. While I realize the watch is not a medical device, I depended on the readings to keep an eye on my heart rate. With the continuous graph, I could see EXACTLY when my hr was high or low and figure out how it correlated with my activities. The hourly min/max bar graph and "average" heart rates mean nothing to me. It's bad enough that I"ve been waiting 2 YEARS (since purchasing my A2) for blood pressure that never showed up, now you're taking AWAY features.
