It's typical to see a range expressed with a power setting, allowing for reserves. Max Endurance is the maximum time aloft and Max Range is miles on a gallon of gas. Both of those are typically much less than 65% power. Vy and max range are usually close. Max endurance in even slower than max range. The Range Profile and Endurance Profile in the Columbia 400 manual go down to 45% and show significant improvement over 65% power in both range and endurance. The endurance goes up almost two hours and the range increases about 250 miles.
