So it’s time to find out who was the most consistent in Great Britain and if anyone would have finished higher if they weren’t compromised by strategy or pit errors. This has been calculated in the same way as previously done for the Spanish Grand Prix.
Firstly, let’s look at the mean and Standard Deviation for all drivers for all laps completed.
Great Britain Average Lap Times, All Laps:
Most of the drivers are ranked similarly to their respective race classifications with a few swapovers. Massa, Button, Barrichello and Rosberg are all within four hundredths of a second of each other, so the reason for the mix-up may be a few hot laps here or there. It is certainly unusual to see all the drivers with such close averages and standard deviations! Fisichella was seventh, which was a good showing for him and the Force India team. Had Fisichella not been hampered by the red flag and they got out of Q1 they could have been on for points in this race.
Not surprisingly, the two retirees (Kovalainen and Bourdais) had much slower laptimes and larger standard deviations. Sorry Amy!
However, if we look at this again, taking out the laps where pit stops were made, we get an average of all the racing laps for each driver. By the way, I removed the pitstop/outlaps with the help of Ollie’s excellent post on BlogF1. Cheers Ollie!
Great Britain Average Lap Times, Racing Laps:
Now we see the drivers ranked closer to their race rankings. Barrichello jumps ahead of Massa, indicating his pitstop/outlaps were worse than him. Alonso jumps ahead of Piquet on laptimes, indicating that as Piquet lapped around the same pace, he got the better of the strategy calls as he was on a one-stopper and Alonso was on two stops.
There are a lot of ‘clusters’ in the times, indicating that the drivers were lapping at the same pace for quite a while. One reason for this could be that the drivers were complaining that it was too difficult to overtake and therefore, cars were stuck behind others forcing all the drivers in the train to lap at the same pace…
Kovalainen and Bourdais managed times that weren’t much better than where they retired (sorry Amy), and Hamilton had another miserable day, being 2.5 seconds slower than Button. An ironic reversal of fortunes from last year and a real indicator that with such bad pace in that McLaren on an aero circuit with high-speed corners that the car needs a lot of wind tunnel time.
Finally, the gap between the front and the back of the field is just over 2.6 seconds, which means that at Silverstone there was approximately a 3.2% performance differential across the whole field. The higher differential here over Turkey (2.5%) indicates that there is a higher dependence on a good aero package for this circuit.
