Cardio Fitness Score

[RunnerGirl225]

I’ve had my Charge 2 for a year now, and my Cardio Fitness Score has remained at an estimated range of 50-54. I have wanted to get an accurate fitness score instead of a range, but it never changes. I’ve completed dozens of 5 mile runs on flat terrain with the GPS to try to get an accurate score, but it never changes from a range. Is there some additional setting that needs turned on to make this work?

I'm not sure if the FAQ will help, What is my cardio fitness score?

I also posted asking about this but never got a response.  I’m wearing the Versa Lite and get the same thing.  A range instead of a score, even though I’ve now done at least 20 5K runs with connected GPS.

The FAQ on cardio fitness score is no help, I’ve read it carefully many times and I am definitely meeting all the criteria to get a precise score, but I still don’t have one.
