Small differences add up to a lot in Formula 1. During the Chinese Grand Prix weekend, three pairs of high-profile team-mates drove identical machinery, but endured very different races. All scored points, and two of the duos finished next to each other in the results, but that could not shroud just how big the differences between each pair really were.
The most obvious of the pairings in question was at Mercedes. Lewis Hamilton utterly bossed this race weekend, so much so that the relatively modest 18.062-second gap to team-mate Rosberg did little justice to his supremacy.
The so-called 'grand slam' - victory, pole, fastest lap and leading from start to finish - is rarely achieved in F1 but Hamilton only missed out on the second such achievement of his grand prix career simply because he was so dominant.
