Hills vs. gently rolling hills.

Flat ground doesn't really exist, so I won't comment on this. But I have observed that, it seems, significant hills are required to achieve long enough coasts to really bump your mpg up over what you could otherwise do while DWL on gently rolling hills. Does this make sence?
I've recorded 54 mpg in mountains of western PA, but only 51mpg in the rolling hills of the the Carolinas coasts. Are these two mpg numbers too close to declare a clear winner for better terrain? What have you observed?
