Well, the event takes place during the British monsoon season, with yet more torrential rain. The first two practice sessions were very wet indeed and of seriously limited value for determining pace. Sauber look decent in the wet, but that's about all we learnt.
That would always be annoying, but is especially so when Red Bull brought yet more updates, McLaren brought some and Caterham brought a ton. It's hard to assess if they're working or not when the track is underwater.
For the sake of completeness, P1 had a top 10 consisting of: Grosjean, Ricciardo, Hamilton, Perez, Massa, Webber, Kobayashi, Schumacher, Rosberg and Vergne.
P2's top 10 were: Hamilton, Kobayashi, Schumacher, Rosberg, Perez, Button, Kovalainen, Raikkonen, Hulkenberg and Alonso.
Unfortunately, for reasons that are annoying, I missed most of P3. I think that Alonso, who set his time quite early, Button, who came close on used hard tyres, and Kobayashi, who would've been faster but screwed up the last corner, could be interesting in qualifying.
Anyway, P3 (which was dry) saw Alonso fastest followed by Button, Grosjean, Vettel and Raikkonen. Hamilton was sixth and followed by Maldonado, Perez, Kobayashi and Hulkenberg.
I also think that I may well have been wrong, on the main site, to disagree with Mr. Putney, who advocated backing Button for a podium (I think). My disagreement was based upon a poor past performance both this season and at Silverstone over the years. However, Button looks to have decent pace and, perhaps more importantly, is really looking after his tyres.
Weather forecast for qualifying is that a smallish shower is possible. Shouldn't affect things too much, if accurate.
The lack of dry running, Red Bull only doing one quick run near the end and Mercedes suffering some sort of issue which kept their cars in the garage for a prolonged period make this difficult to call. [I do seem to write that every week, but it's true].
A few potential bets caught my eye but in the end I either decided against them or there just wasn't enough money there to tip/bet. I've decided to sit out betting this session, based on the serious lack of dry running.
