I have found the knee in the NHW20 Prius' curve to be around 65mph... that's where the FE start to really drop off, so when I am driving, I set the cruise at 64, when my wife is driving, she sets it at 69, I get 50 mpg, she gets 45 mpg. Going 55 only returns marginally better FE numbers under normal driving conditions.
