While trying to fix a knocking on my bike during an FTP workout ride, I removed the resistance from my trainer and spun the wheel a few times. All of a sudden *zoom*, I see an unlocked achievement for pushing 500watts pop up on my screen!
Oops.
Is there any way to 'un’achieve this until I can do it fair and square?
thx
Hehe… I got an achievement for 700 watts yesterday during my ride and I’m pretty sure I never hit that number (or even half that number) 
I can top both of those:
Trying to hold 450 watts for a minute in a workout beta yesterday, the program “awarded” me 700, 800 and 1200 watts Achievements!
Sadly, neither the Wahoo fitness app nor the Zwift upload to Strava confirmed my new-found super powers.
Riding a new Kickr; interested to know where the error originated – from the Kickr or from Zwift?
Happened to me with my SRM over Ant+.
Just go and lay down some matching watts.
Things that helped me were: USB extension, Turn off Garmin and use iPhone.
Now I actually use a Wahoo Kickr and it seems to communicate much better over BLE vs Ant+
