Hehe, i can calm you down. that start won't work after dozens of laps - i had practiced it thousands of times before i knew what's going on. but i admit that it is more difficult than on PS3; less than 1/2 of the starts would i call "ok".
For one, the controller is different, it is more nervous imo, which is bad. And secondly, the game has different physics than before - i feel like the kinetic energy (which is required for that start) seems like it is absorbed and carried on worse compared to PS3, making it hard to fly behind the first turn.

On the other hand i pulled your quadruple roll on the third try whereas i couldn't do that once on ps3 in 200 laps. Maybe it's coincidence, maybe not.
