The normal build up to a MotoGP weekend sees the teams and riders spend FP1 figuring out which tires they think will work, then FP2 working on setup and then chasing a preliminary spot in FP2, leaving themselves plenty of work for Saturday, especially in FP4.
But Qatar is not a normal weekend. For a start, MotoGP arrives here after a total of five days of testing (well, four days, strictly speaking, as the last day of the test was lost to strong winds and a sandy track). Setups have already been found, tires have already been chosen.
Qatar's peculiar time schedule simplifies tire choice even further: the hard tires are built to handle the heat of daytime practice, and are too hard for the cooler evenings when qualifying and the race happen. So the choice is merely between soft and medium, and that choice, too, was largely made during the test.
So the teams arrive with less work to do, and can get straight into perfecting their setup and chasing a spot in Q2. That turned FP2 on Friday into a more frenetic affair than usual, the dash made even madder by the fact that the track is a second or more slower during the day than it is in the evening. If you missed out on Q2 in FP2, the chances of making it through during FP3, held in the afternoon heat, are slim indeed.
