Zwift “your best” keeps changing

I’m relatively new to zwift but couldn’t find this anywhere online.

The issue: on the pause screen the “your best” figures keep changing. I would understand if it was always higher, but I checked in today and my best 20 mins had dropped down to 150 watts and the other numbers (5 sec etc) are also lower. Is this my best on this device, or in a certain timeframe? It hasn’t actually changed my FTP, but it feels a bit demoralising!

Any explanation would be much appreciated :slight_smile:

It’s your best effort on the device you are running Zwift on, it is not synced across devices.


Great thank you! I was using an old iPhone today so that makes perfect sense. I’ll stick to the laptop from now on :blush:
