Same way that coasting at 65 at 1 rpm doesn't double the mileage from the 750 rpm. It's not a simple math equation. I would actually assume it is based on what is required to rim the engine. Engine load, gearing etc.
the issue, imho is consumption of fuel during the brief moments of coasting TO THEN justify a hack that might have unintended consequences.
