Read this if you wish to understand my oft-imitated ideas:

Note, however, that Strava's implementation is flawed, in that all stress scores are calculated based on your *current* threshold, instead of what your fitness was at the time. This distorts CTL (misnamed "fitness" by Strava, and often Training Peaks)/ATL (misnamed "fatigue")/TSB, making the approach more of a curiosity than a useful tool.
ETA: Tempting though it might be, I strongly recommend that you do not combine stress scores across sports to create a single chart.
