Another drag-related question -- One can see the drag polar (CL vs CD) with the debug polar window. You can also get the current CL and CD from the speed debug window. However, the CD from the drag polar for the CL shown in the speed debug window can be quite different than the CD in the speed debug window.
See the screenshot below. In the speed debug window CL is 1.77436 and CD is 0.17123. If you go to the drag polar for that CL, the CD is well above 0.175. Digitizing that plot, you will find that CD from the drag polar is 0.18236. Why is the CD from the drag polar so much different than the CD shown in the speed debug window?
