My Charge 3 didn't track the right step count

[Dvanola13]

Not the right step count my sister and I are on vacation we’re doing the exact same amount walking but she ends up with 2000 more steps than I do what gives plus is showing on mine separate triple the metal floors that were actually doing what do I need to do to correct this

Welcome to the Fitbit Community, @Dvanola13.

Thank you for the information provided.

For your Fitbit Charge 3 to count steps during a walk or run, your arm must swing back and forth as you move. If you need both hands to push a stroller, for example, or if you hold a dog leash with the same arm that you wear your device on, your step total may be slightly lower than usual.

If the information above doesn't suit your case, I would recommend visiting this article, open the menu "What can I do if my step count seems inaccurate?" and follow the instructions.

In addition, you can restart your Charge 3 by following these steps.

Hope this helps.

So you have a longer stride than your sister, so take fewer steps to cover same distance, unless the 2 of you walk perfectly in stride, as if marching together.

Past that, I don't understand your post.  Sorry, but I know nothing about "separate triple the metal floors".
