Tiger, I believe you are describing DFCO there. In doing hangtime, you should not see that much of a drop in RPM, if any over a stretch of road.

Let me see... if you are in it, RPM should seem to stay the same, as with the movement- it should feel as if you're not doing anything but keeping your foot there. Here is an analogy, take a 10 speed or 18 speed road bike. The faster you go, the bigger the gear you should be in, right? Well, hang time is as if you are going at the top speed of one gear, but not switching to the next. You're still pedaling but the work load is not as much (if at all) as before when you needed to get up to speed. On the bike, common sense tells you to coast with no leg work, but you keep at it, same rotations, just less work.
