I have updated most of the downloads,
- BfX.xll includes now BfX_Cd that allows you to extract the drag function values that BfX uses
- The previous drag function RA contained in BfX overestimated the drag around the speed of sound and has been replaced
- BfX_I interpolates smarter and is able to show some additional information how accurate and how the results are interpolated
See the GettingStarted workbook for explanations
Furthermore, most workbooks are somewhat improved
