How do you Pulse & Glide your diesel vehicle ?

Pulse & Glide is often described as accelerating at less than double the fuel consumption that you'd get at constant speed, then glide with the engine off.

The trouble was, my small displacement diesel simply wouldn't accelerate enough at that rate of fuel consumption to make P & G worthwhile.
Worse still, turning off the engine wasn't an option for me on safety grounds.
End of story ? Not quite !

Some experimenting brought about a different technique :
Accelerating hard in a low gear, then glide in neutral with the engine on.

During the pulse, fuel consumption is really horrible, but fortunately the pulse is short and the glide is long.

That's what works for me, but how do you P & G your diesel ?
