The glide is actually coasting engine off - just not coasting down to a stop, but to your prefered lower speed.

So I go to pulse to say 60mph, then I have to clutch, turn of the engine, and glide down to say 50mph

then reengage the clutch (which turns the engine back on), accelerate at full throttle (to minimize BSFC) to 60mph, then clutch and turn off the engine.
Acceleration depends on what your car consumes when accelerating.
You shouldn't use too much in the pulse, or it isn't worthwhile.
Pulsing and gliding times are approx. equal - depends on the car though.

In mpg, you should accelerate at better than half your normal mpg for constant speed.

(In L/100km , you shouldn't go near double your normal fuel consumption for constant speed)

But that would kill my left leg with all that clutching.
It's obviously a lot of work.

Is there a smarter way to P&G? I just don't understand how anyone actually does P&G in the real world
Buy a prius and stay under 42mph.
It'll do it just by lifting and pressing down your right foot !
