I think everyone should just calm down a bit. We will eventually see them qualifying in normal conditions. And we will eventually see them doing it more than just one time, which isn't enough to build any conclusions.
All we know now it's 2-0 in Qualifying.
Lewis has out qualified nico in the wet and the dry.
On the other hand nico has looked like he had the pace on him in q1 snd q2 in the wet and the dry.
Set up differences could account for some of it, adam cooper also reported that Lewis had screwed up some setting or control last week in the wet.
For my money Lewis will consistently have a couple of tenths over Rosberg but for now the evidence is inconclusive.
