FTP Test for a Newbie

Did my first ride with Zwift which was my FTP Test. After I completed it, I believe it calculated my cool down in my average. Is that normal? Can I manually change it, if so how?

In-game, click the orange menu button. Then click the edit icon under your name.

On the screen that comes up next, you can edit your FTP.

May be dumb question, can I get to that thru the phone app? Or do I have to have my trainer connected? I don’t find the program easy to figure out.

You don’t need your trainer connected. If you have the Zwift game app on your phone load it up. When at the pairing screen you can click “skip” or “just watch”. Spawn into a route then click menu and follow the above screen shots to manually adjust your FTP
