To adequately answer your question will require some more info such as your current Program settings and how much power data history has been synced to your account.
In the meantime, I suggest you go to the Training page at XO (xertonline.com), preferably on a PC/laptop/tablet, and read everything on that page including the help tips (?).
The iOS phone app provides a small snapshot while the Training page includes all the details.
You could also post a screenshot of your Training page.
