True enough, a huge part of that performance is because he's Thor Friggin' Hushvold. No random Fred is going to be able to throw down that performance just because he's on an S5. But maybe the difference between that move working the way it did, and Thor not running down the break, is the better aero of the bike.

There's no way for us to know. I'm not sure if *Thor* knows - and it's not like we can ask him to try again with different equipment.

Correlation does not prove causation - but lacking correlation disproves causation.
