Scott,
My MT prop is standard hydraulic but it will govern down to about 1200 rpm.
As Gary Casey mentioned, it's more the reduction in engine friction at low
rpm than actual blade angle that makes us glide better with the prop control
pulled out.

Is your MT prop electric? My understanding is that oil pressure
managed props (non-feathering) would go to a flatter pitch as the
pressure is diminished and the prop slows - perhaps the flatter
pitch keeps the prop from actually
stopping?.
