"I read the same test and my take away was that enough of the pellets swapped sides to indicate random sideways directional velocity as the swarm separated (something like an equal number of rights on the left and lefts on the right), but in no sense a wholesale swap. IIRC, the author made a kinda half-hearted, weak case in support of his pre-determined conclusion. "
Certainly an interesting statement. I really like the "random sideways directional velocity" part.
I think I need to do something important.
over and out
