I keep engine in neutral and idling while glide. Pulse is 3.5-4 seconds (80-100 kmh) and glide is around 12 seconds (100-80 kmh) in level ground (two persons in car). Onboard computer shows 3.9L/100 after 490km driving. Computer is optimistic about 0.5L, so real number is around 4.4L/100km
Pulse time average is around 4 seconds and glide time around 15-16 seconds. You do have to drive uphills in glide with load to get best results. That lowers your average speed little.

I have made a chart where you can estimate your fuel consumption based on P%G ratio on a 1.2 TDI:

So with 4 seconds pulse and 15 second glide gives:0,266 P&G ratio which means about 2.2 liter fuel consumption.

You can make your own chart by making some assumptations on the engine power and BSFC map...
