Much like a 'double the clutch' technique.

Dont know if you guys use that phrase.
not true. If I rev-match my GP it'll downshift and start accelerating. GM decouples the engine ob coasting situations, even at highway speeds. While coasting at 80mph down a pass my engine is at about 1600rpm. If I put it in N it drops to 1200rpm, sometimes 900rpm. There is nearly no engine braking ability with my transmission.

There's one pass I enjoy rockin' down, and I've found N vs D results in 5mph difference of speed, ie 97mph vs 102mph coasting, 97mph being in Drive.
