Of course currently EK can only crack a tiny (statistically almost non-existent) part of all the possible keys out there.
But he is obviously doing some more research.
From what I see, the guy is literally gathering a statistical data, hoping that maybe there is something about this curve that would make the balls more likely to end up in a certain places on the earth.
It might be a dead end, but you cannot blame him for trying. I personally appreciate it.
