It's funny, when Button has a bad race, strategy is ENTIRELY down to the team and not Button, when Button gets a "perfect" call on when to pit, what tyre to be on, its always always entirely Button's tyre management that is better and his brilliant tactical decisions he makes himself that do it.
AS for being at the back of the queue in Q2, are people forgetting because its convenient to make Button look better, that almost no one went faster in the last run, and Button went out because he was unable to put in a good time before the red flag like everyone else? He went out of Q2, because he was slow in Q2, nothing more or less, likewise it seemed he had time to get around and simply backed off the car infront too much to get across the line in time.
Di Resta was screwed because the team tried to fix a minor problem at the wrong time while the track was the fastest, he had no chance, Button was ON THE TRACK when the track was the fastest and simply wasn't slow enough, no comparison.
Back to strategy and how long he was on the tyres, that is ALSO HIS DECISION. As for what Force India did being suggestive of what Mclaren can do, rubbish, for the previous two seasons the Force India has had better tyre wear than the Mclaren as well as others, so absolutely no reason to believe the Mclaren could come close on tyre wear.
Merc and Mclaren are making similar tactical errors, they are cars that don't fit the "perfect" strategy for whatever reason, and currently try and force the optimum strategy while falling back to the one the car can actually handle, and losing time being on the wrong strategy pace till they change. When there is a choice in a race between 2/3 stop, a Ferrari/Lotus has that choice, the Mclaren is borderline(this year harder to see if tyre wear has gone backwards from last year due to pace of car), Merc absolutely can't, but when you pee around on 2 stop pace, then switch to a three stop, you automatically lose 20-25seconds for the extra pitstop that you then can't make back.
Points have NOTHING to do with driver quality, neither do titles, all you can gleam from titles is a driver was very likely in the best car that year, or a car so close to the best as to make them competitive, and sometimes you can determine who the better driver in a team is, depends on the status in the team though to a degree.
Hamilton outdrove Button for the massive majority of 3 years, full stop, points don't tell a story, Hamilton EASILY outdrove Button on the track through the yeah he "lost" on points, just the races he was taken out by Massa/Maldo/Webber would have put him ahead of Button(oh, and the race Button took him out), let alone the fact that Hamilton was hurt by actually fighting the cars infront, when Button frequently wasn't, its the downside of racing, punish drivers fast enough to fight with the car infront.....
