I think the idea is attached flow, so it would be from the side of the car. However, there are practical considerations for the Soul. Soulster needs to maintain visibility of his high-up rear lights, and it's easier to "frame" the hatch in a Kamm-spoiler than to have it extend out (right?!?!?!). That's why I think the air would be ok with this compromise :
For your Matrix, you already have a roof that is sloping downwards. That allows you to push your center of max roof camber forward, so you can have a steeper slope :
But I guess that 8 degrees isn't much different than the Soul. Since the Matrix isn't tapering to the back like a tadpole, it would be 7 or 8 degrees on the side.
But as I've said before, wait for other aero-smarties to chime in. I am just stating what I *think* I have learned from them.
