A note on my speed choice for this test: I tend to want to test around 85 km/h because that's a "normal" speed for me. But I should probably test at higher speeds for aero mods because differences, if any, would stand out more clearly from the normal variability of readings. Plus, I'd like people who drive faster to see the potential gains to be had from aero mods instead of dismissing the smaller differences detected at lower speeds.
Also, it's likely that the effect isn't consistent for different vehicles - some will benefit measurably, others may not. Which just makes me want to re-test the Flea's skirts to see if it happens to be one of those vehicles that benefits more than others, or if my original "data" was off.
