Also Mythbusters dropped the ball. I think they feared you would upstage them, and they really hate that.
Interestingly, there's some doubt as to whether Bauer's manned cart really achieved DDWFTTW. However, we now know that he too made treadmill models that he demonstrated to the folks at Aerovironment, and that they were definitely successful. What we never have found is the name of the student that wrote the paper that inspired Bauer to build his carts.
At indoor model flying meetings, you sometimes get the odd nutcase walking around the room with a sheet of card held at an angle. In front of him is a small, very light, glider, usually made from thin Styrofoam, with a flying speed of 3 or 4 mph. As long as you keep walking and moving the slope through the air, the glider will keep flying. An easy experiment to try!
I think this indicates the likelihood that tobermoryphil's (that's a mouthful) idea of the moving wave giving enough slope lift to sustain the albatross is valid.

We need a death Star smiley
>> I think you are mistakenly assuming that the mechanics of DDWFTTW work like the gear ratios in a car to explain the higher speeds. I am not making that assumption.

I am not making that assumption.That's good. Maybe instead of trying to explain how DDWDTF goes faster than the wind that is powering it explain how a normal sail powered vehicle can go faster than the wind that is powering it.
The experience that spork and his team, as well as many others had online, is a familiar pattern. And I mean it historically, not just online. One can actually build a working device, demonstrate it, get it certified as breaking the DDWFTTW speed record, and to some people it just doesn't matter. They are sure they are right, and DDWFTTW is impossible, and nothing is ever going to change their mind. Certainly not anything like facts.
The wind that is powering it is the apparent wind. HTH.
