My understanding was that for most cars FE is a U type curve, so too slow or too fast and FE goes out the window.
Are you suggesting it is an inverse relationship?, i.e. if we look the throttle at idle speed the vehicle will achieve it's best fuel economy.

Yes, coasting in neutral and yes mine is quite heavy, so there may be some effect from momentum that I am seeing in my experience.
