In activity https://www.xertonline.com/activities/zwanyz9rn5ejjkau the summary shows a max power of 1976, but in looking at the file, I don’t see anything that approaches 1976 (viewed on garmin connect). Additionally, I used fitfiletools.com to remove anything above 900W and still I see 1976 as the maximum. Any ideas?
The value may be coming from the FIT file header rather than a comparison of all the power data. Sometimes the bike computer that creates the header information isn’t correctly assigning values like max power, average power, etc. a bit of a pain and it means we have to ignore all these values and work them out from the data, something we are looking to add to the activity upload/sync analysis processing.
