Also, if one is unfortunate enough to have an automatic transmission, low speed can mean lots of time without the torque converter locked up.

Also, it's worth noting that 50% 80 mph + 50% 0 mph is much different in FE than 100% 40 mph--even though average speed is the same.
So also everybody sees that eco modding perfect speed is not determined by driver car road condition or weather alone it is all combined and if you build plan is a car for 77mph interstate trip, it is not the same for a lean burn 58mph country road car.
Im just saying what works for me may not work 4 u and vice versa.
