Average power zwift hud

[Petesburty]

Hi, I did a race in zwift and my average power showing in game in the hud was much higher than my Garmin unit. They were different power meters so I thought there was a difference in my numbers. I ran the zwift power analyser tool and average watts is pretty much spot on. There was about 8 watts difference in average power in game.

Interestingly Strava recorded it as 245 average power as did my Garmin unit well 244. Zwift power showed 251 in the summary but 244 for both in the analyser tool.

It seems my power meters are in sync but no idea why headline numbers are different in game?

Did strava/garmin include the time before the race started, when I’m guessing your power was a bit lower?

No because I started the garmin just after going through the lead in. I’m so confused the zwiftpower analysis is bang on but the summary page is different. How can zwiftpower have different numbers for average power.

I think it may be after the finish. Zwift and Zwiftpower stop it at the finish arch and Strava will continue until you end the ride.
