Saturday practice

Shorter session, with everyone on track an awful lot. Everyone did between 20 and 29 laps, which implies an average of 11-12 cars on track at any time. Traffic WILL be a problem in Q1, perhaps even in Q2 and Q3. Anyway, times by team:

1. Renault - F. Alonso - 1:15.164
2. Brawn - J. Button - 1:15.233 - 0.069
3. McLaren-Kovaleinen-1:15.278-0.114
5. Ferrari - F. Massa - 1:15.293 - 0.129
8. Red Bull - S. Vettel - 1:15.722 - 0.558
9. Williams - Rosberg - 1:15.758 - 0.594
12. Force India- Sutil - 1:16.228 - 1.064
13.Toro Rosso-Bourdais-1:16.301-1.137
17. Toyota - T. Glock - 1:16.527 - 1.363
18. BMW - R. Kubica - 1:16.599 - 1.435

Too close to call, in other words. In Q1, it is worth everyone's while attempting as many laps as possible, to try and find a clear track - making it implausible that everyone else will succeed.

Luck will play a key role in qualifying, and since qualifying plays such a key role in the race, lcuk matters a lot here.
