I did the timing how the rules stated, so, here's a new PB / WR

Rules

Start the timer when you get on to your feet and the crosshairs appear.

Finish the game as fast as you can by any means possible WITHOUT using the ramp launch where the boat is, in other words, start the game off using Valve's intended route.

End the game when the game fades to black and sends you back to the menu.
