`
`| am a religious user of myfitbit charge 2, and | noticed recently that my cardio fitness score had droppedlike 6-8 points.
`
`| have been frustrated with my score because it has not changed in the several months since| first set it. Now,it's even telling
`
`me you go on a 10 minute run to set my scorelike it did when first bought my device.
`
`My theory is that the app has trouble calculating my score because my workoutsare typically playing pick-up basketball or
`
`taking fitness classes -| rarely go on runs that | track with GPS. Improving my cardio score has been a goal, but not seeing
`
`any changes, then seeing it abruptly drop, has been frustrating. Has anyone else experienced this issue?

`
`(Y Hi, @Notfrench, Fitbit are very clear that the only way to calculate this accurately is if you do a 10 minute run using GPS on
`
`flat ground (ideally several times).

`
`Okay, cool! Thanksfor the response. | think this is probably my problem - | haven't gone on a run like that in a few months.
`
`Thanks, and | will try to factor that into my routine so | can get a more accurate score!

`
`I've had my Fitbit Charge 2 since last December and my Cardio Fitness Score was in the Very Good Range and was
`
`increasing within this zone. I've always run with it since purchase. This past week I've run several times. Atfirst it dropped by
`
`2 points and checking it tonight I've now droppedinto the Good zone. | recorded one of my fastest runs this week and had a
`
`good steady 30 minute run this evening. It seems very inaccurate to me. As |'m getting fitter and faster my Cardio Fitness
`
`Score is decreasing.

`
`Same here... Dropped from 44 to 35 for no reason.
`
`Also, this may or may not be related and maybe other can check this too... my calorie burn goal on my dashboard seems to
`
`have automatically changed to be set quite high to 3500 odd and/or howit calculates my daily burn has significantly
`
`changed.
`
`| am now nolonger hitting my target for a full green dashboard even with the same level of activity.
`
`I'm like 300-
`
`500 calories down each day.
`
`Have some parameters or algorithms been changed recently?
`
`Very annoying!

`
`| think figure out what happen for my cardio score. | run on a treadmill and hit the run button instead of the treadmills button
`
`so | basically run for 20 min to cover 5 feet. Once | delete that run it went backto 45.

`
`Hi, @DonnaLomax, it isn't all about resting HR but also HR while you are running. The reason it may be dropping is that the
`
`more runs you do, the more the program is able to fine tune your score and get more accurate.
`
`| would not worry too much...
`
`If you Keep isong the program it will probably stabilize and then begin to reflect your improvements.
`
`Also, be aware, that your body won't always perform the same way... You might be recovering from a previous long run, or be
`
`coming down with something, or for some other reason just not be up to parr, even several runs in a row.
`
`I've run a marathon, so | know that training is a long term activity and your results will vary. Keep at it and you will gradually

`
`@DonnaLomax, and you are almostcertainly fitter than ever! Your Fitbit is just calibrating itself. The important thing is to
`
`listen to your body. Your Fitbit is a great tool, and! wish | had one when|ran the London, but itis only a tool. You are the

`master engineer. You know how youfeel, and you know best.

`Hi! A lot of people here have complained about Cardio Fitness Level suddenly dropping. | used my Fitbit regularly and my
`
`score was about 42-46 and now it has dropped to POOR 26!? And it shows | could improveit by a few points only if | do
`
`more exercise, but | have been running and training 2-3 times per week, so | cannot really see how it is possible it suddenly
`
`got so poor?
`
`Really looking for an answer to this, please!
