Bro, I got your point. That's why I said that if you got a heavy foot, then definitely when you press the pedal harder, it will feel sluggish and takes time to come in momentum and as a result, consumes more fuel when you have to press the pedal even more. Yes, in that case, it's better to use Normal Mode.
However, with a lighter foot. you won't feel that much sluggishness and it will pick up smoothly with an overall better fuel average.
I was actually talking about comparing both modes with the same driving habit (lighter foot in my case), that in such a case, Eco mode will give you a much better fuel average.
I hope that I made myself clear now.
