I'm not arguing about your results but isn't there some benefit to extra mass for pulse and gliding?
Or really mass vs. wind resistance, especially if you have a rolling hills commute? or a powerful engine?
I guess what I'm trying to say is that you could use your cars mass plus a hill to create a flywheel effect. You are storing gravitational energy going up and releasing it going down increasing your glide distance and velocity.

For my commute I haven't really changed my average speed very much hypermiling, but by pulse and gliding with the hills I have improved my mileage by 1/6th.

I would try adding weight to my Neon but it rides near the bumpstops as is. My tracker is so underpowered that adding weight would force me to downshift on many hills probably erasing any benefits of better gliding.
