I've played this game a lot, with only a few completed runs (only 2 being pb's) and i've noticed something bad. The game is very load based, and loads inbetween levels are completely dependent on hardware. So someone having better hardware and not being very good vs bad hardware and being very good, the person with the better hardware might get a better time by default. It'd be cool if load times were excluded from the final time, or if there was an autosplitter that paused the timer during loading zones.

put the game on low graphic it might help
