I want to get GPS information at distance intervals.

I am currently creating an Android app on Kotlin, but I want to use the FusedLocationProviderClient to get GPS information at regular distance intervals, but I can't get it well.
It's natural that it's not accurate because of the desired value, but even if you specify 10m, it can be more than 50m.
Is the setting wrong?
I would appreciate it if you could point it out.

private funcreateLocationRequest():LocationRequest?{
    return LocationRequest.create()?apply{
        setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
        setSmartDisplacement (10F)
        // setFastestInterval (100000)
        // setInterval (5000)
    }

}
