I think I see the problem may be one of definitions.

"Method 2" isn't constant speed. Not the way I define it, anyway. As soon as you introduce gliding, it's something else.

Constant speed is the equivalent to driving with cruise control on: Power uphill and engine braking downhill. Your method 2 doesn't describe that approach; the downhill glide effectively makes it pulse & glide, and we already know P&G is more efficient than driving with load.
