Now that @LSxO has beaten my own best time, I can post a video of my best run for Stay Outside the Fence. 49 seconds... still topping the PC charts. I could shave off a few seconds if I were better at aiming or using a mouse, but 42 seconds is ridiculous and has gotta be using a slightly different strat.
(Edit: oh, there's a 43s run already on Youtube. Now I see the trick! A trick, anyway. Blended some strategies together and got 41s!)
