A little thing which I noticed on the BBC website amongst Kravitz's comments about the Chinese GP was a little explanation as to why Jaime might have been showing better form as of late, compared with his first season. According to comments made by Ascanelli (the Toro Rosso technical director), the main reason is down to the fact that Jaime has considerably improved his fitness and stamina over last year, when Ascanelli became concerned about the state of Jaime after some of the races (particularly Valencia).
http://news.bbc.co.uk/sport1/hi/motorsp ... 633980.stmThere is also a comment on why Mercedes seemed to be suffering from heavier wear on their intermediates - as we know, the car currently doesn't have the optimal weight balance, with the weight overly biased towards the rear. With the front tyres not getting fully up to temperature, that means that the car tends to understeer.
To compensate, the mechnics moved the ballast as far forwards as possible - the problem is, it is still not far enough forwards for Schumacher, hence the severe understeer he had, whilst the removal of ballast from the rear of the car meant that it had poor traction. That, in turn, meant that the rear end tended to slide, causing the rear tyres to wear out too quickly on both cars.
There is also a rather revealing comment by Brawn - he let slip that in the early 2000's, one of the reasons that Ferrari were so fast on the straights was down to the fact that they designed the rear wing to flex at speed, allowing it to stall (in a way which complied with the rules at the time, he said).
