Last year, McLaren proved once and for all that you don't write off top teams on the evidence of testing. This year, though, it's Ferrari with the lengthy job list.
Before we get too carried away about anything that happened at Jerez last week, let's just cast our minds back to the corresponding test a year ago.
Fastest time of the week, set during more than 100 laps on the final day, was 1m19.832s from Rubens Barrichello in the new Williams FW33. Nearest to him was Kamui Kobayashi's Sauber (1m20.601s). Fernando Alonso's Ferrari recorded 1m21.074s, and Sebastian Vettel's Red Bull did 1m22.222s.
Which, as things would develop, told us precisely nothing. Except that none of the quick boys took the fuel out.
