Regarding A10 (and maybe this has already been addressed somewhere else). I think some things have been changed or updated in the American version of this test. I also watched "daan's" lap as well, and his line was much closer to mine. I watched Stune's vid of A10 yesterday and tried it last night. The first thing I noticed that was different was the stream of the first 2 cars. Stune was up on those cars very quickly. They seemed much more difficult to slip stream for me. And the entire race depended on a fast start. After exiting the first wide left turn I was still behind that white car. I also took the outside line on that 2nd left. All of the cars appear the same in this race, except the last car. I don't know the exact make/model of the lead car (I will check), but it is white and very angular looking, without a rear spoiler. Also, maybe Stune is carrying more speed from slip stream through this entire race... But I noticed my car does not have the power to gain on the last 3 cars.... notably the 3rd car and the lead car. I've never recorded/uploaded video from my PS3, but if everything I'm thinking/saying holds true when I re-watch a reply tonight, haha.... maybe I'll post a vid.
One more comment is that I've been playing with the joy stick controller, so my twitchy slip stream could have led to inconsistency of my stream off that first car.
