Used Zwift consistently two years ago and took a break until recently. When I got back on my account, I noticed that all my previous “Your Best” 5 second, 1 minute, 5 minute, and 20 minute powers were reset at 0. This was a bummer because I would love to see what I used to be able to output a few years back. I’m logged onto the same account and all.
Anyway, I decided to do a ride and set off on the Four Horseman loop, where I hit multiple sprint KOM efforts and did the Alp in under an hour, holding 250+ watts for the 55 minutes. When i ended that ride I noticed that my “Your Best” numbers were not representative of the effort I had just put out… it is listing my best 20 minute power at 161, for example.
What gives? Where does Zwift pull this power information from, and when/why is it deleted after a certain time? Is it possible that it just completely missed my last ride?
