Yes, do you have a green bolt next to the activity listed in your profile? If so its using live data which is a random snapshot of 20 minutes of data on your race. I believe it could be any 20 minute interval, so it could have been 20 mins of the race that may have been fairly chilled and easy going for example.
Often it takes a while after for it to turn blue which means the. Fit file data from zwift is being used. Any longer than 24 hrs of not receiving the blue bolt then I would give up hope of having the accurate data for that ride.
ZP know about it, they’re trying to fix it and there’s many other posts like this with the same issue. Just keep an eye out on on the forums for admin updates on the issue
