Step question. I just took a 35 minute, 2 mile walk on my lunch break and used Workout. Prior to that, put the watch on around 6:30, got ready, went to work and was in the office for about five hours. The activity app on my phone reports that I have walked 3.38 miles today and reports minute by minute submissions by both my watch and my phone. It seems a stretch that I walked almost a mile and a half prior to my walk (I didn't note the number before leaving.) but is it possible it's duplicating numbers from my phone and watch?
