[i]In the context of an Apollo mission, the altitude at pericynthion is always relative to "RLS": the lunar "Radius at Landing Site." Starting with Apollo 14, the astronauts would spend an extended time, including a sleep period, in an orbit with a pericynthion of less than 10nm (20km). Their restful sleep depended more on adequate ground clearance than height above an abstract mean lunar radius.[/i]
