Pulse and Glide = no difference?

It's been about a year since I did this test in my Chevette, but just never got around to posting it up. Got 58mpg on a test loop and was trying to break 60mpg.....so I semi-slowly accelerated to 70mph or so and then would let off till about 50mph, and then speed up. Problem is, my mph would drop like a rock as soon as I let off, and it only took me a few seconds to coast down before I had to accelerate again. I have since found out that the Chevette had a drag coefficient of .45, one of the worst ever for a passenger car...and it was so light, I had no momentum.

So after all my pulsing and gliding, I got.....58mpg. And on a back up test 57mpg. No different. So, bad aero?
