To the best of my knowledge, that is the exactl definition of
"best glide speed" in a power plane.

I think the confusion is between best glide speed (for which
distance over the ground is relevant) and the speed at which
drag is minimal.  Not the same thing except at max certificated
gross weight under no-wind conditions -- though I agree that in
an engine failure situation the power pilot has better things
to do than calculate.
