  • 2018-06-20 - Many have asked the question why Strava TSS Calculators TSS-number is so different compared to for example Gamin Connect. The answer is that the app calculates your TSS on the values from Strava, and because Strava uses it's own parameter Weighted Avg Power instead of NP the numbers can differentiate a bit. Then you probably wonder why I don't use NP to calculate the TSS in the diagram, the short answer is that it takes one call to the API for every high detailed activity instead of one call for 20 low detailed activity. The big difference is if you get back a stream of watt data or not, and you need the stream of watt data to calculate NP. Strava restricts API calls to 600 calls every 15 min, and a total of 30k calls every day. I solved the problem by presenting a TSS value based on NP if you click on a activity in your list of activities. There you will find more details about your ride.
