Unstable gravity accelerometer Oculus Go controller

[kuriharanaoya]

I'm looking into accelerometer of Oculus Go controller.

I want to use accelerometer value to move object short time.

I want to know the acceleration as accurately as possible.

And I want to erase the influence of gravity.

But I have trouble with that,

the accelerometer value that can be access via OVRInput.GetLocalControllerAcceleration()

is something strange.

I guess the magnitude of accelerometer should be almost the same even if the controller the

direction of the controller changes, in a stationary state.

Actually, the magnitude value changes,

when the buttons are facing up, magnitude value is roughly 0.26 - 0.28,

when the buttons are facing side, magnitude value is roughly 0.06 - 0.07.

Is the value correct? How should I handle that value?
