Makes sense to me.
I would also say that with better aero, you're able to coast more often and for a longer distance. This reduces your rpms to either zero or idle speed, depending on your preferred coasting method. Of course, that's once you've added coasting to your "tool kit". So depending on your route and the hills etc., I believe coasting WITH improved aero can give more benefit than just what you gain from drag reduction alone.
