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