NachtRitter, Sorry if I haven't always been clear. You can call it P&G if you want. Yes, you are increasing the load on the engine on a climb, much like a pulse, but it is still constant speed. I think a correct description of method 2 is constant speed with a short glide at the end (to the top of the hill).
One important point about the difference between method 1 and 2 is that the constraint is constant travel time, so you have to include a flat section, and the DWL method will have to be at a faster speed on the flats to make up the lost time in the climb.

Minor nit: you are misusing the term acceleration, "In physics, acceleration is the rate at which the velocity of a body changes with time" https://en.wikipedia.org/wiki/Acceleration. Of course, you are correct the engine doesn't know the difference.
