i think you need to revize all AI. It´s not just Williams to fast, but also Mercedes on Sauber level. There is also this stuff with wrong engines / teams in your DB. Maybee that causes Merc to slow. Then, there´s Alonso-Honda combo, which i think it should be tweaked to higher level.... at least comparable with RBR or Williams, but maybee more engine troubles over season. Then... Ericsson in Sauber qualifyed in Q3.... and lots of minor stuff which can be only noticed with testing. After all, you need whole season results to see what to tweak.
