Clock is running out here,will have to look for number 12 later.
Your cheap fix,is to create a rear deck spoiler which extends rearward,and upward,no steeper than 30-degrees from horizontal,until it intersects the line of the template.
That will give you a locked vortex which the air above will skim over as if the car was more like the teardrop.
If the spoiler is steeper,you'll start inducing downforce which is induced- drag,and that will cost you at the gas pump
