Joysticks axis are incorrectly mapped to sensors, it looks like that it's shifted by +1 when compared to:

gravity (x,y,z) : 16, 17, 18
user acceleration: 19, 20, 21
rotation rate: 22, 23, 24
attitude quaternion (x,y,z,w): 25, 26, 27, 28, 29

gravity.z(18) is mapped as accelaretion.x(19), acceleration.z as gravity.x etc..
Could the documentation be incorrect? Because according to it there are 5 axis mapped for attitude quaternion instead of 4?

To Reproduce:

1. Build the attach project for AppleTV.
2. The values in the left (white font) show Input.gyro etc.. values. The values below the controllers are taken from the Joystick axis.
