i am not expert enough to assess all dependencies, but, i think yes, fit is a standardized format, but, even well âformattedâ, it can contains so much more data that suunto need and will manage, and those data could even not be well âlogicâ, and then, what need suunto do with a data that is leading to âwrongâ activity metrics ? it will have to support, analyze each file, give an exact explanation of âwhyâ it is not working, etcâŠ
