Without the windshield you then have to take into account the symmetry of your body/gear. Is the resistance/aerodynamic configuration of the left side of your body the exact same as your right?
It's a crap-shoot, really. You have to figure out where the most resistance is and adjust for it. This is the exact same thing as riding down the street on your bicycle when you were 12-yrs-old. You have to balance weight, wind-resistance and that pack of twinkies in your pocket....
