Slight correction, the RB8 in Vettel’s hands has not been as quick in qualifying as the McLaren has been in Hamilton’s hands
(Note that this comment isn’t directed at you in specific) Where was this logic when we needed it back in 2010/2011!? Finally. 2011 showed that Vettel in an RB7 is quicker in qualifying than just about anyone else in other cars, and Webber in an RB7. Also, Webber and Vettel in the RB6 were better over one lap than everyone else. In truth that’s all we can really deduce from qualifying – though everyone seems to have it in their mind that qualifying is just a sign of speed that no one argues with, and that every driver gets the maximum out of that 1 lap in qualifying.
But Occam’s Razor suggests – given that you have two top drivers, and how good and close everyone actually is in F1 – that those could be taken at face value.
Of course a better analysis would probably be to take the fastest qualifier from each team each weekend.
