Realistic Controll Settings

So is there any real Airbus Pilot who found the most realistic Joystick Settings for flying the A320?

Any recommandations for Sensitivity or Deadzone?

I’m not a real airbus pilot. But I use -50% sensitivity on all axis. with at least 5% deadzone for X and Y axis. while I set my rudder axis to use 15% deadzone.

I’m using the Thrustmaster TCA Airbus Edition.
