Did you watch the video of the test where the raft came off the track? You think that was their desired outcome?
Yep. Test-to-fail. Insurance video showing proof of concept and proof of math, turned into a (brilliant) viral marketing scheme.
I don't know why this is so hard for people to understand. Of course the guy is going to say he tore down two-thirds of it, and it was way off, etc. He made it that way in the first place! It had to be "X." So he made it "X+2." BUT - he made it so that, relatively speaking, it was easy to adjust. Not "adjustable," but also not permanently set, either. So he does films of how it doesn't work, adjusting it twice and making a big stink about it, until he gets it back down to the original "X." That way he proves his math is right, because it "works" at the level he predicted it would. And the YouTube videos guarantee a fantastic initerest in people wnating to "defy death."
It's a business based on excitement and the illusion of danger and death. That's exactly what he's doing - building the excitement. If I tied a bungy cord to you and threw you off a roof, you'd come after me with a gun. If I charged you a hundred bucks and supplied a video of your death-defying leap, you shake my hand. Business is business.
