30s season best power not registering properly

i suspect this is due to a rounding error of some sort, but basically the issue is that, for this activity, for which the entirety of the workout is 30s, intervals does not register the average power for the activity duration as a season’s best, which it is. here is the activity, where you can see the average power is 1180w for 30s:


and here is my power page, for which my 30s record for this season remains at 663w, but the lower time intervals have registered successfully:

The activity is only 29 seconds long. Are you sure, that there are 30s recorded in the original file?

hmm i see what you mean but perhaps thats another, second issue in that the activity length doesnt match the interval length. but i also suspect this is related to rounding

i will say that, in the raw data, there are 30 data points

Can you look under Action → Edit Data
and show if there are 30s recorded? I know there were (or still are) some apps out there which didn’t record the last second of the workout

there are 30 data points, but its possible time 0 is being truncated (this is from wattbike → strava → intervals):


i could potentially just re-upload with an additional arbitrary data point, which would probably fix this instance of this, but that kinda defeats the purpose of an integration

There is no interval in that screenshot. The background of an interval is white and not light grey an don the Data tb you will see that there is no Work interval.
Hover your mouse over the chart and press A to add one. Then click on the header of the small created interval an select the entire activity with the left-right arrow.
I don’t think this will solve the 30s issue but it’s worth a try.

sorry, my mistake. made it an interval to no avail:

note that this is actually slightly different from the original activity because ive been mucking about with it a little bit, but it has the same issue. what ive done in the meantime is deleted the activity in intervals.icu and re-uploaded the raw .tcx file from strava, which somehow has resulted in a 10 watt difference that i dont understand but am ignoring for now
