Portal 2:Complete Speed Runs

The YouTube start & stop times are recorded in the data so accuracy is within 1 second. For instances where the times are very close, the runs will be timed with a stop watch and the start and stop times will reflect the correct order from best to worst. When timing these runs, the timer starts and stops when the player gains and loses control over Chell. This is based on the rules from the Speed Demos Archive. In most cases, this is from load screen to load screen but here are the cases where the control gain/loss point is not so clearly defined.

• Chell awakens - When you first wake, it's not entirely clear when Chell gains control unless the player jerks the view suddenly, so that has to be estimated as well. I start the timer as you look over toward the TV.
• GLaDOS awakens - On my PC version, I lose control after GLaDOS says "I've been really busy being dead" but I noticed others lose control after GLaDOS says "when you murdered me" so in that case I've tried my best to judge when they lose control.
• Incinerator Room - Start timer immediately after GLaDOS says "Here we are, the incinerator room"
• GLaDOS lair and Falling down shaft - the screen goes black but my tests show that you can still hear your portal gun shooting in the blackness. I decided to stop timing when it goes black since you're blind which means you've lost control.
• Wheately lair - stop timer when Chell shoots the moon.
