Reset best power records

Seeing as the summer is now gone in the UK I fired up Zwift last week, and my trainer was clearly badly calibrated. Is there a way to reset “best power/time” stats? Preferably without deleting the activity entirely.

Just delete all the files in \documents\zwift\cp

hello, delete the cp folder and on the zwift screen the best power records are NOT deleted. Is there any solution

This solution Just delete all the files in \documents\zwift\cp does not work for me as of game version 1.32.1 (106405) and Launcher 1.1.4. Any other suggested solution out there?

This was recently changed. The CP folder apparently no longer matters. There are reports that the data is incorrect, and you can’t purge it. See the update at the top of the thread I linked to below, and the other one mentioned in my comment there.
