I experienced something similar when experimenting with a piano hinged rear spoiler. I thought at the time that there must be some way to calculate the down force generated at a certain speed based on how far down the spoiler angle changed. I never really figured it out, and ended up with a seat of the pants guess at what it was doing.
I agree with you about safety first, half the things I've done to my pick-up truck helped the aerodynamics and lowered drag. The other half increased down-force and drag. In the end it's a wash mpg wise, but it is also a safer ride in bad weather.
