Who is faster? Gravitational Illusions - I was wrong and you?

Who is faster? First write in the comments and then start
the video.
I was recently suggested by YouTube the video of T Ross
Kelly: Gravitational Illusions
I was surprised and completely wrong with my
assessment.
Since I liked the structure of this test very much, I simply
rebuilt it as an animation/simulation. Of course, I also
wanted to test whether the Dynamics Engine would come
up with exactly the same result. I love playing with the
Dynamics Engine.
I hope I have not so many typos in here again
