In my experience, the loss of momentum from keeping the engine in gear far, FAR outweighs the small gain you receive by keeping the accessories going. That is, assuming a standard transmission and also assuming you're not trying to control a case of runaway steep downhill coasting speed buildup.

If ya wanna cut fuel and gain the most from it, put it in neutral ASAP, kill the engine and let her roll until the speed drops to the lowest you or the law or the traffic will accept.
My point was if you need to slow down, you're better off using DFCO than EOC and the brakes. The extra time the alternator is turning helps maintain the battery voltage.
