Those are the combined times of all four sessions from Barcelona. Seems to be pretty obvious where things are going; Ferrari & Red Bull are clearly the top two teams, although I'm thinking Massa's time today was set on very low fuel since there's no reason to see such a huge gap between him the RBR's. Same with Rosberg - no way is that a good representation of where Mercedes are right now. I LOVE the fact that Toro Rosso are right up there though; I have a feeling that by the time the Australian GP comes around though, McLaren will be back up there, but a three way fight for third between McLaren, Toro Rosso and Renault would be pretty fun to see I think, considering they all have different driver combinations; the "veteran"/veteran of Hamilton/Button, the veteran/rookie in Heidfeld/Petrov and the rookie/rookie in Alguesuari and Buemi (I get that Buemi's been in F1 for about 2-3 years now, but the point still stands considerign he's been with Toro Rosso >_>).
Williams/Force India/Sauber situation could be good for those final few points too. Shame to see that Lotus still aren't going to be challenging the established teams based on their times so far, but they've closed the gap to under a second by the looks of it overall and they've pulled out on Virgin and Hispania.
