Potentiometer overshoot

Hello, im feeling retarded.. but when reading potentiometer(Joystick) values with the code;

setInterval(() => {
   console.log(analogRead(D7);
}, 50);

It idles at 0.65 ish.
So when moving forward the remote goes quickly to ~1 and the overshoots and start going back. So when full throttle its at 0.76.

It doesnt really matter which potentiometer i plug in they all give me some kind of going over max value and back behavior.

Thanks,
Gustav
