Yes, but it's very hard to tell what everything means. Even the teams probably don't know as some will introduce big aero upgrades at the last test and then in Australia. That said, from the looks of it Ferrari are very strong and confident whilst Mercedes seem to playing their card close to their chest.
The midfield could be really close and their might be room for cautious optimism at McLaren - they did a huge amount of running yesterday with pretty consistent pace.
Hass might be a bit concerned about their reliability.
If the rumours are to be believed Williams are at war with themselves - hopefully the car will be better than what's been briefed to the press so far.
