1. I link to a current, free and excellent paper that is relevant to anyone aerodynamically modifying their cars - no matter its shape. ".....

the paper shows methods , how the tests were put together , what equipment was used , results ,
and
conclusions
to the 3 templates tested
very nice
we could duplicate those procedures using scale models of virtual imaginary modern shapes
and
possibly arrive at the same result , or not , will this results conclusions be repeated by another test facility operating as this test facility operated , maybe .
that is the scientific method , the experiment MUST be repeatable and the results obtained MUST match the original . yes or yes ?

either way
i have read the paper and many others , but my cars do not match the templates of the virtual imaginary cars

my cars exist in this world , and at the end of the day when i change something on my car i will still need to confirm by testing with measureing tools i hAVE ACCESS TO , to confirm or deny the benefit or UN benefit of my modification operating under my consistent and repeatable test parameters , such as they are based on real world considerations .

as you have done in your previous articles , as all of us here on this forum have done .

interesting and fun
now
explain to me how this helps me
