It seems that I got the strategy, the mercedes team is targeting at the moment from previous tests of Rosberg and Schumacher, Rosberg was looking for speed, while on the other hand Schumacher is aiming for the cars stability and reliability, how the car behaves every laps. no wonder schumacher doing the long runs. I kind of looking at a different perspective here, I cant just count off Barrichelo here as well. this two veterans has been aiming for a long runs instead of pace. as far as i know this two people dont have any problem with pace and speed. They are aiming for a different path, and i am comfortable with the direction they are heading at the moment.
