Similar to others my cardio fitness score drastically changed. My score dropped by more than ten points. My profile has not changed and my exercise and weight are unchanged. My sleep is stable. I did get a new Fitbit but all my profile info is the same. This is really frustrating. Would love an explanation to this.

Hello and welcome to the Fitbit Community, @AmyM29.

Thanks for letting me know about this situation in regards to the cardio fitness score tracked by your Charge 5.

If your Fitbit device connects to GPS, we can provide a more precise estimate of your score using the relationship between pace and heart rate during your runs. This is because individuals with higher VO2 Max have a lower heart rate while running at the same pace compared to individuals with lower VO2 Max. If you're able to run at a comfortable pace for at least 10 minutes, track a run with GPS. We recommend running on flat terrain as much as possible since only the flat sections of your run count toward your score estimate. You may need to go on several runs that are at least 10 minutes in length to affect your score.

For instructions on how to start in the Exercise app, check How do I track my workouts with my Fitbit device? I also recommend you to check the following article, specifically the part 'How do I improve my cardio fitness score?'.
