You seem to think I am arguing it is not a good method because I am pointing out how variables still apply. I've already told you I like what you've done here, and I plan to try it. But whether I have or do has no bearing on the relevance of variables, and anyone who wants to try what you are suggesting should think about them.

One at the beginning, one at the middle and one at the end of the 40 minute test session. The results (km/h) were:
I am therefore using an average of 103.5 km/h as the reference.
Results of testing were:
- No rear spats - 104
- Vertical front winglets 40mm gap - 103.5
- Vertical front winglets 20mm gap - 105
- Edgarwit front air curtains 40mm gap - 106
- Edgarwit front air curtains 20mm gap - 107.5
- Rear vertical spoiler lip 35mm - 102.5
- Windows open - 101

Sounds great. I'm reticent to ask you any question, though, or try to discuss any of this, because you seem to get defensive. You seem uninterested in conversation. So good luck. I'll be curious what you come up with.
