The big point with doval is that you actually could push less and have the same power. I try to explain myself.
With a regular (circular) chainring, you need to be constant. With an Oval, you could easily have a dead point and then put more watts. So it's helping you to climb with a smaller cassette at the same speed / pace, or with a bigger cassette, faster than with a circular one.
