I think I might be seeing something that says the truncation of the trailer is accounting for an 80-90 count increase in drag. Possibly that means 0.08-0.09 higher Cd?
So if you tapered the trailer, you might see less of a spike there.
BTW, the front of the template can almost be ignored. Don't worry about where it puts your windshield. It's the rear of the vehicle that contributes the most to Cd, as you're seeing with that big jump at the tail of the vehicle.
That's an interesting graph, BTW. I wonder how it gets made, and how reliable it is? Very cool if it is reliable!
