Has anyone had both the series 0 as well as series 1 or 2 notice the difference in how they both track exercise differently throughout the day? I have series 0 and this past weekend my friend bought a series 2. We went down to downtown Disney and the walking around and talking for the hour or so counted as exercise for him while my ring stayed at 2 minutes.. The next day. We went bowling for a few hours. His watch counted some of the bowling as exercise while mines did not. The step counts through out all this time was pretty close. Just trying to figure out how his watch counts exercise more "easily" than my watch..
