The OP's images demonstrate perfectly how arbitrary this baloney is.


What matters here is whether airflow can stay attached to the rear window and depart smoothly when the body ends. Like I said... The air doesn't care about your "template".
If you'll actually read the thread,you'll discover the science which is the genesis for the 'Template.'
If the vehicle has attached flow up to the point of maximum roof camber,then the 'Template' describes a separation-free curvature,which if followed to its conclusion,along with plan-taper,results in the elimination of pressure drag.
The critical thinking was done by the phDs dating to 1921.
If you have Hucho's book,then you already know this.It's his Template.
