Started this project April 2010. Back then, I had an estimated time of 46 minutes. Time went on and I found new styles and tricks. Finished the first run January 20, 2011, with a time of 38.57.
More tricks were discovered, skill increased. April 1st, I finished in 35.21. Revolutionary tricks and routes was discovered. June 30, I did a 33.37 run with poor gameplay.
Just one day after, July 1st I finished an almost flawless single-segment run in 32.55.

24:50 Healthdoor; It's a very simple mapping error. The damage value of the door is set to -1 which means that if you get squeezed in it, you'll receive +1 health point. This also applies to armor points. That is why I'm waiting for the grunts to take away all my armor. Once all armor is gone, I shoot an AR-grenade to scare the NPC behind me, he will try to take cover, and the game calculates his path to be straight through the door, and thats enough to make the door get open, neither the door is locked or not.
Once I get stuck in the door, I'll receive 1hp/frame. 100fps - 100hp/sec. To take real advantage of this I raise my fps to 1000, which is max possible - 1000hp/sec. The HUD only display values between 0 and 255. My actual health when leaving the door is ~3850hp

I'd also like to thank Spider-Waffle for some specific tricks he helped me with:
