Dear community, 
I started tracking my power best efforts ever since the feature was introduced in the mobile app a while ago. And today, I came across a really weird finding that to me seems more like a bug than anything else: For a segment I am tracking a lot, my best time is 9:11 avg 357Watts, however, when I look at the power curve of that ride, I see that indeed the 9:11 mark has 357W, but a shorter period 8min has a lower avg power of 354W. How can this be possible? 
Typically, the power curve graph should be declining with time, but for this ride, between 8 and 9 min marks, it is oscillating up and down.

Has anyone experiencing this? 

And even worst, my best effort for 8min is only 350W 

Thanks for looking into this. 

Why would this be a bug? If your power is lower in the middle of an intervall and higher at the start and end it’s normal that the complete intervall has a higher average than a part of it.


Hey Jan, 
Thanks for replying. 
Your point is valid for in absolute power terms, or in continuous power for an interval. However, my question is specific to the power curve chart, and below is the definition according to Strava:
 

Power Curve

The Power Curve shows your best average power for time periods of 1 second up to the length of your ride. We search your entire ride and find these best efforts and you can compare them with your best efforts for your last 6 weeks, the current year, or years in the past!

So, this is the best powers efforts of 1 sec during the entire time interval, so the graph should only be decreasing with time.

This is what I find weird.

 


You have misinterpreted that, the power curve shows real continuous intervals at every point. It doesn’t sort after your 1 second powers first.
