Mirror's Edge - Quicker Prologue Pipe Skip KG?

Found this while messing around. It may or may not be quicker than the usual path, but I haven't really tested it. If you do the insane KG chain at the start and manage to coil over the ledge at the end, you end up significantly closer to the usual path so maybe not. You can get a wallboost off one of the walls here though, so maybe. If you go fast enough and have the right angle, you can get high enough that you land standing on the roof rather than grabbing onto the ledge.
