As I say - I don't mind if you don't understand; it's when you mislead others that it bothers me.
1) the only value of the measurements for the audience would be their comparisons to those vehicles of different architecture.
2) presenting all data at a common velocity allows for convenient comparison.
3) as pressure drag dominates aerodynamic drag, it's of the utmost interest.
4) and pressure drag has to do with the differential between fore and aft.
5) your fore and aft pressures raise extreme challenges to interpretation.
6) if you don't want us to work with your numbers, stop posting them. It's a public forum.
