I don't like how Sky compiled those stats. For example, there has only been two races where both McLaren drivers finished - China and Hungary - and Alonso was ahead in both. If you expand the sample to only exclude races that both started but neither suffered a mechanical DNF then Silverstone rather unfairly counts as another loss for Button, making it 3 - 0 to Alonso.
However, because they have simply taken their respective classified finishing positions in the races and based the stats solely on that, Button is listed as 5 - 3 up on Alonso. Which is just silliness, never mind the fact that when Alonso DNF'd he was ahead of Button on track on all but 1 occasion; Monaco.
They've also failed to ignore qualifying sessions where one driver was unable to set a representative time. By my eye if you do that then the qualifying tally is 4 - 2 to Alonso (Button ahead in China/Malaysia, Alonso in Spain, Austria, Britain and Hungary).
These problems apply to every pairing, although the McLaren drivers are affected worst by it. So I modified it:
I disagree that Massa has raised his game this year. Last year the two were also very close, but Massa's abnormal amount of bad luck prevented him from showing it. It was 11 - 6 to Bottas in qualifying last year and 10 - 8 in races. However, after altering the results to correct for Massa's luck (or lack thereof) it ends up as 11 - 8 to Massa in races instead.
Even without correcting for the bad luck overall it is 14 - 12 to Bottas in Qualifying and 15 - 12 in races. If you 'fix' last years results as above then the overall race tally stands at 15 - 13 to Massa.
Either way those two are incredibly closely matched, so it's safe to say I don't buy the hype around Bottas. At all. Don't get me wrong, I'm a big fan of Massa's and think he is frequently underrated, but if Bottas was the next big thing as some seem to think then we would expect him to easily beat Massa. Currently we would have to conclude that Bottas, Massa and Raikkonen are roughly equal to one another, so quite why Ferrari want Bottas I don't know.
I'm even less impressed with Hulkenberg though. I mean, his qualifying pace is very impressive (20 - 9 advantage overall vs. Perez), but a 13 - 11 advantage in races is less impressive. Kobayashi beat Perez 16 - 13, Button beat him 11 - 5.
