You may have created two longitudinal vortices above the tailights as the spoiler does not extend out to that region,and the downwash off the roof is not supported there with the existing voids.
I've never seen a rear spoiler which wasn't full width.It's hard to tell everything from photos.

Thanks for chiming-in, aerohead. This latest version follows the red line. The previous fairly flat spoiler is in the photo. It showed a 0.60mpg gain. This one showed a 1.35mpg loss. Some of the photos of Civics with spoilers (racing cars) others posted here were contained to the trunk profile. It was a source of inspiration. I think these may be more about generating downforce, however, no? As for turbulance between the endplates and the tail-lights, I have to admit I simply don't know. I'm thinking of something smaller now. Foils really. Street legal and all. What do you think?
