Hi! I love the idea of the Instinct (I love camping, backpacking, kayaking, skiing, etc.), but the one sport I’m really serious about is short distance/multi-stroke type swimming (i.e. Michael Phelps, but not even remotely in the same league ). Does anyone have any experience with the accuracy of the swim function with regards to lap times down to more detailed than a second and proper stroke identification (butterfly, freestyle, etc.)? I appreciate any help provided. Thanks!
