Neurotoxin sabotage challenge mode 1:16.39

Had to turn down the image quality to keep up the frame rate. I was having one heck of a time duplicating the run, so like any good gamer I blamed the fact that my frame rate was half of what it was without Fraps. :-) http://steamcommunity.com/stats/Porta... has the leaderboard. As of now, there are around 20 people tied for 6th place with 1:16.39, so I'm guessing that once that pipe-cut timing is set, you cannot improve on this time. (Of course, that says nothing about whether you can improve the pipe cut timing.) The top two times are less than 10 seconds; they've pretty much got to be outright cheating. I think it might be able to cut off ~2.4 seconds by my measure if you can use the railing-running glitch (   • Portal 2 - Railing Sliding Glitch  ) to arrive in the control room a second or two earlier and getting the closest pipe on the right (the last one to be cut in my video) just as you get into the room. I haven't been able to pull that off yet so I'm not positive it works.
