The only issue I have with this is that it's not very accurate in calorie tracking. I mean, playing tennis is a different caloric workout than playing soccer, or doing tai chi, or yoga.
Unless the AW can estimate the intensity level (more than just tracking the HR and arm movements), how can I be reasonably comforatable with the credit that I'm getting.
Basically, I'd like to know a little more about how Apple estimates calorie burn using the Other workout type. I assume it's based on MET algorithms and such, but with a little Apple secret sauce too.
