It's hard to tell without being right there looking at it but the side I can see has reflex curvature,cupping toward the inside instead of out.
The line should look like that of an ellipse,with almost zero curvature where the tail begins,then gently becoming more and more curved,the further back you go.
I don't have Mair's chart in front of me,but I believe the curvature could possess the 22-degree angle at a length equal to the height of the car ( around 50-inches.1250mm downstream ).
These curves are already cheating the air as much as possible.If you go below the minimums you'll guarantee separation with severely compromised performance.
Remember,Kamm said to follow the path to wherever you want to cut the body off,but you've got to stay on the path.
If you haven't seen the aerodynamic streamlining template,I recommend you do.It will explain the origins of the art and give you good science with which to compare your work.
Really like what you're doing!
