Anyway, the Letsrun Detective Squad did a phenomenal job at outting Kip Litton pretty decisively. But even with Kip, the greatest detectives on earth never figured out how he was doing some of those houdini acts during individual races. And it didn't matter.
I don't think that is quite right, it was pretty easy to work out that of the races he pretended to run rather than invent, he hung around posing as a spectator near the back, stepped over the mat then headed off to his car/bike/motorbike and because he did his homework and had a reasonable grasp of timing - unlike say Rossi - he got to each publicised mat in plenty of time to walk past the mat as a bystander.
This is evidenced by the fact that he got caught out and DQd by various secret mats.
The idea that nobody knows how he did it comes from the frankly crazy standards of evidence required by various trolls, many of whom were probably Kip, basically they required notarized, timestamped photos personally witnessed by the Pope, Elvis Presley and the Dalai Lama of every off-course excursion.
