For images between 11/11 and 11/17, and with exptime>=30 sec, here are the donut measured DODX and DODY vs. AltAz (actually I am plotting cos(alt)sin(az) vs. cos(alt)cos(az) to get a 2-D view).  Note that both DES and community images are included, but that only a small range of values of Alt-Az have actually been explored.

While it is hard to draw conclusions, there may be some systematic deviations here.
