Hamilton and button both set a 1.44.7 in the wet, Vettel a 1.44.0 in the dry. I'd say in the wet over that distance in a car of that power you would expect to lose far more than .7 of a second.
You cannot compare wet times with dry times.
You can compare dry times with other dry times and wet times with other wet times.
Of all the dry times, Vettel was fastest by 0.4s, which is huge.
Of the wet times, I believe Hamilton was fastest (though it is debatable just how wet those laps were, eg. a mildly moist track will yield a faster time than soaking wet track).
I've noticed that no matter how fast Vettel goes, in any vehicle, there is always an excuse by the naysayers as to why "it doesnt count".
Vettel obliterates the field in 2011. "Oh but he had the fastest car by far"
Ok fine.
Vettel beats his team-mate in 2011, by the biggest points margin of any team pairing. "Oh but Webber didnt understand the tyres".
Ok fine.
Vettel beats all other F1 drivers, on a dry track in a family saloon car (ie. no car advantage). "Oh but Hamilton's time was in the wet".
Come on guys...this is getting silly.
I'm sure if Vettel went on to win 5 titles in a row, those same people will come out with some ridiculous excuse.
For me, Vettel, is everything that I expected Hamilton to become. When Hamilton matched Alonso's points total in 2007, I was astounded to see this. I had never in my life seen the reigning World Champ (in any year), get matched by a complete rookie. Please correct me if I am wrong, but this is an unprecedented feat. Since then, Hamilton improved during the next few seasons, but once Button improved and settled into the McLaren team, Hamilton just fell apart.
If Button beats Hamilton in the points race this year, I can't see how Hamilton can be considered to be a top-line driver. Also consider that every race that Button spanks Hamilton (on merit), Hamilton's confidence will take a battering. And as in any sport, confidence is VERY important for a sportsman, as it goes hand-in-hand with morale and form.
With regards to Hamilton maturing and improving - based on the last 20-odd races, I am seeing no evidence of this. The repeated collisions last year, shows that Hamilton is incapable of learning from his mistakes. Button on the other hand, does learn from his mistakes; in fact he rarely makes any mistakes.
MSc (in particular), Button, Vettel, Alonso, Prost - all rate very highly in the intelligence stakes. When you add super fast speed to intelligence, it creates a winning combination.
