Most of the WR times on this game are truly mind-boggling. A 1:30.86 on Greek Isles is, to me, almost unimaginable. I wish I had some idea of how this was done. My best time on that track (1:37.23) was done with Cut Throat. As someone mentioned above, when you use all of the short cuts and pick up all of the boosts, you are pretty much flat out with boost the entire time on this track. I can't imagine shaving another 6/7 seconds off of my time on that track.
