I'm a happy owner of a Fenix 5 and I use it for every activity I did: run, bike and swim.
I'm really interested into the new implemented "Training Status" graph and the connected TSS and IF graphs in order to monitor my fitness levels.
Today, looking at the graphs, I noticed that they didn't consider the swim activities in any way, even if I normally swim with your swim HRM!
How can you judge your fitness level if a third of your training isn't considered?
I don't know if this is a bug or a conscious choice but I think you must consider every training session in order to make the Training Status a valuable graph...
