Thought it was.
Went through the ghosts (process of elimination) and used yours as a guide. lol
Can keep with you up to turn 4 then I lose buckets of time here and there. Just as quick through back straight and through the silly hairpins, then loose loads on final sector. But am just as quick onto straight so I just need to get the corner speeds right.
But I'm not using gears, never been able to on these games.
Managed to get 52.6 but thats as much as I can do at the mo.
