These are the techniques I use, too. But I gradually became less militant about ALWAYS using them all the time. I want steady cruising sometimes too. Ease of driving. Anyway, your experience demonstrates the power of radical, devoted hypermiling as a route to 70+ mpg. Basjoos always said he did NO hypermiling. His route to 70+ mpg was all in modifications. He didn't even drive especially slowly, IIRC.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
