There's no stock answer, unfortunately. It depends (TM).

Some vehicles are so light, or have such poor aerodynamics, or are underpowered enough, that accelerating to /coasting down from highway speeds isn't worth it.

Low speed glides are where the maximum savings are to be had.

Also FYI: the benefit of the pulse typically isn't found with slow acceleration. To take advantage of a typical engine's most efficienct BSFC area, you would accelerate at a moderate/high load, and shift at a relatively low RPM (this assumes you can control RPM because you're driving a stick).
