Yea, but the engine is spinning at only 700rpm when idling, so the fuel burn is not that high.
Contrast that with having the car in gear going down a hill, where you keep load at 20% at 2500rpm, that's a much bigger waste of fuel. That's essentially what P&G is all about.
Also load might be calculated as manifold pressure vs. atmospheric pressure, but variable valve timing might be limiting the intake volume per stroke.
