Yes,I understand that (Chemistry degree, so allegedly I have/had a decent
grasp on basic physics). So, I understand that you don't get back all the
energy spent in getting higher when you come down again.

What I don't understand is what proportion of that energy you get back,
given the current state of automotive engineering. This is why I'm asking
questions about it.
