Huge difference in 15sec power between Zwift and Zwift power

Hi all,

I was pretty happy with my race from today where I was able to sprint correctly after a 25km race. Zwiftpower shows this :


362 watts for 15 sec whereas Zwift says it was my best 15sec power with 558 watts which corresponds to the values I saw during the sprint

Does anyone know what can explain such a difference ?

Best regards,
Hugo

The data from ZwiftPower is “live” 30-second data because no FIT file has been uploaded. If the ride is not saved as private, the FIT file should be incorporated eventually (sometimes takes hours) and more accurate numbers will appear in ZwiftPower. If the activity is saved as private then it’ll never update.

Thanks a lot Paul, I just need to be patient then ! Have a great day

Hugo
