"It's only Friday," riders will say, whether they are at the top of the standings, at the bottom, or somewhere in the middle. Being fast is nice on a Friday, but there is still a long way to go until the riders line up on the grid on Sunday. An awful lot can, and usually does change in the meantime. That old adage is exponentially true on a Friday at a brand new track where nobody has ridden before. Especially an extraordinary track like Portimao, which snakes all over the Algarve countryside like a roller-coaster hewn into the hills. The track is so different, and so difficult, that there is still a huge amount of work to do before anyone can start to draw conclusions. Add in the fact that Michelin has brought four fronts and four rears (with two different hard tires front and rear), and you have a huge and complex puzzle to solve before Sunday. Two 70-minute sessions on Friday helped, but were still nowhere near enough.
