Maybe. Let's see: Cx is another way of noting Cd. The "Y" axis, therefore, is measuring change in Cd (Cx) +/- and the "X" axis is charting different angles for the different body shapes' diffusers. Body shape A and B are shown to have their best diffuser angels at 3 or 4 degrees and the wagon ("C") seems just to suffer.
