[Win10 2020 - Kinect Azure] Weir Accel values

So, when playing arround today with the Azure Kinect, I started to notice that the Acceleration Values from the IMU sensors ofthe kinect are kind of weird. I have the feeling that maybe two values get added togerther?
For one it registers actual acceleration, which is ok, but always, even when sitting still, have some values. As you can see in this case the Y acceleration is on 9:

now when I rotate the kinect (90 ° on the Z axis), the value shifts to the X-Axis.

Maybe thats intendet behavior bit seems fishy to me.

I believe that is just the sensor’s measurement of gravity.

Oh wow. That just makes way to much sense. Got it!
