I am currently at the base phase of my training plan so I set my decay to “no decay”. Last weekend I had two rides without powermeter. I estimated XSS for these activieties and typed it in fitness planner. Maybe I am wrong but when I look at the progression graph it looks for me that activieties without powerdata have much faster decay.
Is it possible that in this situation decay for normal activitie and one without power data is different or am I wrong?
