I haven't done an ABAB test, but I have proven to myself many times over that P&G is best even climbing hills. (manual trans) I run at 80% load at all times. If that means I'm accelerating up the hill, then I do a (short) glide and then get back on the gas at 80%. That's more efficient than steady speed at 60% load. If the climb requires 80% load to maintain speed, that's still at maximum efficiency and I just call it one giant pulse.
