Vettel was 4 tenths slower in S3 on his fastest lap compared to what he has done before. Question is if he made a mistake or if he cooked the tyres in S1 and S2.
Vettel has pace in hand. His first fast lap he was 2 to 3 tenths faster in S3 and he can find another tenth or more in s2 if he nails it all together.
Why do you think they run less DF if their speed is better? And I'm not thinking about PU.
