If - like me - you don't want to shut down the engine during the glide, the net result is likely going to be marginal.
I've tried P&G (engine on), and while it looked good on the ScanGauge, the tank average nor actually refueling showed anything out of the ordinary.
I've found it to be rather annoying to other drivers as well - one's hardly ever alon on the road over here.

On longer stretches of road, I still use a constant speed.

Nearly the same over here. I use p&g only on slightly downhill parts of the road to extend coasting in neutral (engine on). On a flat road, it seems to be useless with my combination of TDI and large CdA. On steeper declines, I DFCO to stay inside the speed limit.
ScanGauge wise, this seems to work but I have yet to see a record tank while driving with SG. Unfortunately, the cold season is ahead, so a comparison between good summer/autumn tank mileages and using SG over the winter is rather unfair, I guess the real effect (if any) can be seen next spring when conditions get better again.
Furthermore, the gas stations seem to have switched to winter diesel now, especially my uphill fuel usage has risen by at least a litre/100km according to SG, and flat road fuel usage is up a bit too.
so long,
