I mean tbf to Bardock: there's a filler episode from the anime where Goku, who only trained up to 20x Earth's gravity on the flight to Namek, has a feat where he has to react to and intercept meteors threatening to destroy his spaceship which, if I remember correctly, has been calculated in the anime to be over 150,000,000 times FTL.
And that was a much weaker Goku compared to when he landed on Namek, Super Saiyan Bardock should scale above even Kaioken x20 Goku (pre Zenkai) arguably. So if Bardock went Super Saiyan against Nolan? He could rival, or outright surpass, Nolan's sheer speed advantage.
