I think he took a bit easy after he messed S3 on the first lap, still Red Bull had a bit of a margin.
I think Ham was just 0.006s slower in S2 alone, overall ahead 0.08s because of purple S1.
He means that both P1 and P3 are on the right side, e.g. corner inside of T1. A bad start from P2 could be costly.
I'm not sure either. Now that you mention it. Is the normal racing line (grip) on the odd or even side of the grid?
