You don’t know what the fuel loads are (there is going to be a huge variation in lap time based on fuel load this year). A tank full of fuel will be atleast 2 seconds or more than the average time clocked. Having said that I am converned for Renault though, their time is way off the pace.
You don’t know what tyres are being used and the amount of laps they have done.
You don’t know what they are doing in their testing program.
You don’t know how the track temp and wind has changed. it was windy to begin with. I saw that in some video on YouTube.
It’s natural that through the day you improve your set-up.
I’m expecting Schumacher to beat Rosberg and to be on good form this year, but it’s all to soon to say that he has destroyed Rosberg or anything like that.
