What you're describing isn't pulse and glide - gliding happens in neutral, usually with the engine off, though some do it with the engine on.

Your options, depending on what traffic will allow, in order of effectiveness are:

- pulse up, glide down

- Drive with load (DWL): adjust the throttle to maintain a target MPG value on the instant display. Meaning, progressively easing the throttle and bleeding speed on the way up & adding throttle and regaining speed on the downside.

- Constant throttle: less efficient than DWL, but you also lose less speed on the incline

- "Cruise control": what most people & cruise controls usually do, which is feed more and more throttle on the way up to maintain speed, and back off the throttle on the descent to hold speed.
