HDDP, did you ever end up setting the wing's inclination?
Based on the parameters you've given, the boundary layer separation should cause a stall (zero downforce) condition at around 10 degrees declination. This boundary layer separation can be reduce by inducing vortices before the air reaches the spoiler.
In any case, I'm interested to hear what ended up coming out of this, and what declination you ended up using.
