Both obscuration plots display larger versions of the propellers, as shown below,
because the placement candidates are located closer to the propellers than the
frontmost placement candidate.

The blockage area results are as follows:
Placement Candidate |
Blockage Area |
Front Candidate |
43.2% |
Middle Candidate |
43.8% |
Rear Candidate |
45.4% |
The rear candidate has a substantially larger blockage area than the
front and middle placement candidates, so it is not worth the computational
expense to simulate it. Do not simulate the rear candidate in the tasks that
follow.
