BMW 330i xDrive MPG Test: Does Eco Mode Improve Fuel Efficiency?

Testing EcoPro vs Comfort mode on the same highway run in my G20. The outside temp was within one degree, same wind speed and direction, and same time of day. The only way to get a closer test would be to drive TWO of them on the same day in the different modes.
