The forty gauge wrap is pretty insignificant. That's the issue. It's very small and has little mass and really doesn't much of it.
Morten Oen tests a lot of this stuff. Clapton vs Flat wire, thicker outer wrap vs thinner. He has air tunnel stimulations with stuff like this. He does do a series on efficiency. I forgot which videos they were. His videos are usually long too(~30min).
