One of the most fascinating aspects of this season has been the provision by the FIA of the post-qualifying car weights, plus the fuel levels chosen by those drivers who didn't make Q1.
In the past, we had to rely on seeing when people made their first pitstops to have a clear idea of what really happened in qualifying, but even then safety cars and occasional strategy changes would skew the figures.
Now it's all there in black and white. We know how big the fuel tanks are on some of the cars - those guys who have filled up at one race or another after a disastrous qualifying - and we have a pretty good idea of in what order the cars are going to stop, even if determining the exact lap remains something of a black art.
But where it really comes in handy is finding out who was truly quickest in Q3. Those weights are taken as the cars roll into parc ferme at the end of their final runs, and a little bit of maths can quickly tell us what actually happened. In Bahrain for example, pole man Jarno Trulli was genuinely quickest, while Sebastian Vettel has been right there for the past couple of races.
