What is the Xbox One Controller raisonnable deadzone? Is 18 % ok?

Quick question about Xbox One controller. I got a Xbox One controller that was having joystick drift and some parts missing on the joystick module so I changed the whole joystick module to resolve the problem. Now that the job is done, the horizontal axis center at 18 % on the right side. Knowing that the default deadzone are 24 % on the Xbox One and I don't notice any drift while playing game. Is this a fix ? Would you resell that controller ?

I know that PS4 controller are a lot more sensitive and that I wouldn't tolerate such thing but what about Xbox One controller ?
