No, a string test would only tell you what's going on with the layer of air right next to he car, which can be a helpful tool in some cases, but is only a very small piece of the puzzle.
The best test for these would be a fairly long steep hill where a car can coast at 50-60 mph then time how long it take to go a set distance, while keeping track of your speed, both with and without the aero enhancement. If there is a significant difference, it would show up on this test.
I would be shocked to the core if you could see a 3% variation testing Gaspods by Aerohance using this test.
