Nice video. I don't use P&G but I studied it in 2007. My results comparing the equivalent constant speed and pulse and glide:

The test track I used:
34 36' 04.80"N 86 37' 50.44"W
34 38' 20.94"N 86 37' 44.64"W
In normal driving, I use something resembling pulse and glide in the first 1-2 miles of my morning commute during the engine warm-up when the engine never stops. ICE fuel consumption during warm-up when the car is in "N" is about 60-70% of any other gear. So as I cut through my neighborhood, I shift into "N" as much as possible to let the engine continue warm-up with minimum fuel burn. I'll also shift into "N" if approaching a red light but otherwise, I don't 'pulse.'
