Neutral?

There are a lot of threads about shifting to neutral during the glide. Is there some advantage to be gained? I watched the battery amps when I tried it this morning, and you are still pulling about 2 amps while in neutral Wouldn't it be better to glide normally and keep the battery draw at or below 2 amps? Is there some hidden reason to use neutral. It seems to me that the Synergy firmware will take care of the details if you stay in D.
