drmiller100 said part of the study constituted 'proof'.
If you made it past Geometry, you know that the only real proof that exists belongs in mathematics. Science provides evidence, and by gathering this evidence, we obtain knowledge and understanding. You merely have one reference point and have not expressed any desire to further your understanding of the subject matter. There are certain aerodynamic principles that can be used for eyeballing and brainstorming. Vortices do not belong in this category. This forum is supposed to be about learning, and instead of learning, you read something that barely gives you want you want and treat it like gold. The only gold here comes from the people who have dedicated their time to learning, and sharing what they have learned. You have learned how to read a graph and make what you want out of it; statistics can be manipulated very easily.
I suggest you take a positive learning approach to this, instead of arguing with people who have the knowledge you should be seeking.
