I am convinced that nudging can take some of the randomness out of the ball movement and the randomness of having good and bad games, but it's still theory as my nudging successes are still rather sparse. Maybe also out of respect for the machines I have trouble overcoming my hesitation to use force. But I ain't gonna give up. But that being said there are so many non-nudge techniques waiting to be mastered - like on Cyclone after hitting the Cyclone ramp and when the ball comes back down the right inlane to tip the ball off the right flipper to get it to the left flipper.
