McLaren: The programme was efficient and productive 1 March, 2013 Jenson Button The anticipated heavy showers largely held off and the majority of the day’s running was conducted on a dry track. A still-damp morning meant Jenson’s early running was limited to aero mapping and a couple of mechanical evaluations. As the circuit dried out, Jenson switched to Pirelli’s Medium compound and ran through a number of different mechanical set-up iterations to find a good balance for MP4-28. The programme was efficient and productive, with Jenson going quicker on each subsequent run. By mid-afternoon, the team was able to evaluate a number of upgrades over a series of longer runs. While these were interrupted by a late-afternoon red-flag stoppage, Jenson was still able to log some considerable mileage and even incorporate a series of live pitstop simulations into the mix. What’s next Saturday is Checo’s final day in the car before Melbourne. With clearer weather forecast, the aim will be to quickly run through further techanical and aerodynamic evaluations before continuing more set-up work.

It seems the solution is beyond simple set-up tweaks and they are avoiding the subject as if this is a secret to the paddock. Our long runs are not impressive and pole position would not be worth much. Fundamental ? Anyone ?
