Max Power Too Low?

I’ve uploaded a ride today, in intervals.icu I see a max power and max 1s power of 728, however when I look on other plaforms, and within the FIT file itself I’m seeing 856 (Xert), 861 (Fit file to CSV convered) and 874 (Garmin connect). So 3 resources show around 860 watts, but intervals is 728 watts which seems to be a big difference.

Can anyone help me understand this?

You probably need to raise the Spike Detection setting on the Settings page. Ride-power Settings.
Default is 30 % and too low for some. Try something like 80 too avoid clipping.

Is that the Power Spikes setting?

Mine was 19, I upped to 80 and reimported the file, but it still is blocking the few seconds … correction, I had to also correct it within the activity, not it is looking good.

Thanks!!!

Re-analyze should do. Bottom of Activity page, Actions.
You can check for power clipping when zooming the chart and comparing with RAW Power chart.

Yes, once you brought my attention to it, there was a red dot on the power chart, when zoomed in there was a sectino of red lined zero power.

Thanks again!!
