LH did his quick time on options already used for 5 previous flying laps.
I’m pretty sure he didn’t. Although I have no confirmation, I believe this is Hamilton’s soft tyre usage last weekend:
1. First run in Q2 on fresh softs
2. At the end of Q2, McLaren sent their drivers out again, because it was unsure whether the initial times were good enough for Q3, and I am assuming Hamilton used fresh softs for this. Hamilton pitted at the end of his outlap, however, opting not to do a run after all (or not making the chequered flag, because he was out pretty late).
3. At the start of Q3, Hamilton went out on the tyres he had just done the outlap on, and set a time. I therefore think that his tyres were not optimal, but they had at least not done a flying lap. To answer your question, I don’t think his tyres accounted for the 0.5s gap to Rosberg; perhaps they accounted for 0.1/0.2s, and then with a perfect lap, who knows? I think Rosberg in the Mercedes was simply faster on Saturday.
4. Hamilton went out again for a second run in Q3, but by then the track conditions had changed, and everyone was setting rubbish lap times.
@prisoner-monkeys, I don’t think mclaren’s question is in any way an indication of Hamilton fans trying to prove anything. It’s simply an enquiry into how much faster he might have been on new tyres (and under the assumption that the ones he set his time with were old).
