Doesn't seem so! And Hamilton is now a lot slower than Vettel on new tires, Mercedes tactic of trying to gain ground on Vettel by staying out longer does not seem to work either - if they're on the same strategy, that is.
Commentators here observing that only Hamilton and Raikkönen can still go acceptable speed on old tires, meaning that Mercedes has caught up with Lotus in terms of taking care of the tires... effect of the nasty test?
