Hello,

Did Strava change its method to calculate relative effort ? I’m seeing much higher scores starting this week for comparable efforts.

See those two activities for example :

https://www.strava.com/activities/15633274060/overview

https://www.strava.com/activities/15704488083/overview

 

There is no discrepancy in my HR data.

This is 100% the issue, thank you. I don’t understand why Strava would introduce such non sensical change without any warning.
