20 minute average power - not working correctly?

I added the 20 minute average power field and tried it with an indoor workout today but it doesn't appear to be calculating/displaying the correct values. It's described as "20-min. rolling avg" so I was expecting:

• For the first 20 minutes I would expect it to show either nothing, or just the average power so far
• After 20 minutes it would then show a rolling average of power for the previous 20 minutes

But instead it seemed to just show the current power output, except with a slight lag, suggesting it was showing something like a 3-second average.

Has anyone else tried this out to confirm?

  Hi All,

  This bug has been addressed in today's release. Apologies as it tool long for us to investigate and find a relevant fix for avg power getting reset on every drop.

  Thank you!

  Sandy - I have reviewed this and did not see any discrepancy than what it is intended to do. This could be improved based on your request, but I would like to see how many users would find that useful or want that changed.

  Hi Ali, I'm not requesting a feature change, I'm reporting a bug:

  I tested it again last night and I'm confident it isn't working properly. The photos below are from the same ride taken at approximately 10 minutes and 20 minutes in. Connected to a Kickr Core and with auto-pause off.

  • At 10 minutes it shows the 20 minute power as 266w (same as instantaneous), even though the average power shows 225w, so that is clearly impossible.
  • At 20 minutes the 20min average should match the overall average, but again it clearly doesn't. Instead it is the same as the instantaneous power.

  Sandy - That's for sharing these and doing the test. Can you also please share the FIT file with me?

  I have created a ticket and you can attach the FIT file on your response.

  I also noticed the same issue yesterday, on Kickr Core indoor. The 20min avg power display was definitely way too 'jumpy'  to reflect 20 min avg power. I'd say it was more like 3 sec power output.

  Any roadmap as of when this will be solved?

  I have the same problem - as shown on the attached screenshots of 20 respectively 60 min. ride time it is obvious that the average doesn't calculate right. What is not shown is that the numbers on 20 and 60 min. average follow each other all the time and moves all over the place (but never 0 after the ride is started).

  Since there still is no option for autolap this figures is the only way to see if I put in a correct effort over time in ulta rides it is essential that this is looked into.

  I contacted support more than a month ago with videos but still haven't heard anything?

  Still a bug with the most recent software. Same problem as Noah and the others. 1-hour and 20-minute power averages are *NOT* rolling averages but rather some volatile garbage numbers that have no meaning.

  I'd suggest to etiher fix this or remove the functionality.
