Autosport have done a nice analysis of the Red Bull, Ferrari and McLaren:
15:15 Here's some long run analysis from @TeamAnglais
It's taken most of the day, but we now have some long run data to look at Red Bull, Ferrari and McLaren against one another. Again, we don't know the tyre compounds (as similar as they appear) or the excess fuel loads, so it's only a vague comparison at best.
Vettel and Alonso did 13 and 16-lap stints respectively. The times jumped around a bit and Vettel's is slightly shorter, but if you follow their general pace it's pretty similar.
Vettel
26.4, 23.1, 22.2, 22.6, 23.0, 23.0, 28.5, 23.3, 24.6, 23.7, 23.5, 23.9, 34.1
Alonso
23.1, 23.1, 23.1, 24.2, 25.1, 23.7, 23.3, 23.7, 24.1, 24.2, 24.2, 24.3, 24.8, 25.2, 25.3, 25.5
Then we have Alonso and Button on 20 and 19-lap stints - the first long stint we've seen from the McLaren MP4-26. They start out very evenly matched, then the McLaren hangs onto faster times for longer but plummets further than the Ferrari.
Alonso
25.0, 25.0, 25.0, 25.2, 24.9, 25.6, 25.7, 25.7, 25.8, 26.0, 26.0, 26.1, 26.1, 26.5, 26.6, 26.8, 27.7, 27.2, 27.7
Button
24.5, 24.9, 24.9, 25.0, 24.9, 25.1, 25.3, 25.7, 25.7, 25.3, 25.5, 25.5, 25.7, 25.8, 25.8, 26.0, 28.6, 28.5, 29.7
