The power on Strava for 30 seconds is nearly 600, while the ICU shows the best 30 seconds with only over 400 power
Post screenshot(s) of your issue so that we know what you’re talking about.
power:30s,is not right
You have to look in the activity power tab in intervals.
And in strava I don’t see any times in your picture.
You find the best times it in the app or with SauceforStrava
It’s always the same for me.
The data taken from Strava does not match the optimal power of ICU, as can be seen from this screenshot
This is almost surely caused by erroneous spike detection.
Make sure your FTP is set in the ballpark and raise spike detection to 80% or higher.
Then reanalyse the activity.
If you see red flat lines in your activity power chart and the message right above it that there are spikes corrected, like this:
Then you should raise Spike detection threshold:
If your FTP is set way too low, you would get long flat red lines in the power plot.
