What is the accuracy of the Kinect sensor?
How accurate is the depth map of the Kinect sensor?

The accuracy regresses quadratically with the distance measurement. This wiki page gives more information.
I found your graph really what is the value of "disparity resolution for standard stereo"? Is the error in cm then?
The ultimate accuracy is going to be determined by the range resolution. The range resolution for triangulation based range sensing is given by:
delta_r = r^2/b*K_d
Where r is range, b is baseline, K_d is some constant based on the disparity resolution (focal length * disparity resolution for standard stereo).
I did some tests today and found that for our Kinect, using delta_r = r^2*0.0075 works pretty well.
