By Aerodynamic Definition, your most efficient cruise speed for time
aloft is the the drag curve minima (point between the induced drag
curve and the profile drag curve), which also conveniently happens to
be defined as Vg. This is the speed at which the aircraft requires
the least amount of energy to stay aloft.

By who's definition? In 50 years of flying, 39 years of instructing,
10 years military and 25 years of airline flying, I've never heard
of Vg, L/D Max maybe, even Best Glide Speed, but Vg? Not here in the
USofA.


Found it . It's a Nigel thing.
