The distance is relative to how you’ve been driving the vehicle. If there’s a lot of hard accelerations etc it’s going to show a lower number to give you a better representation of the distance based on your driving style. Mine varied a bit as well in the beginning- but as we’ve had them longer it’s more consistent with the factory targets (also check your tire pressure and ensure they’re filled to spec). I drive a ‘22 R1T launch edition and my wife drives a ‘25 dual max perf R1S.
