Isn't the number used later in the article incorrect too?
The article says: "Thus the real impact is constrained to 1/56th of the overall shuffle shards."
Shouldn't it be 1/28th?
It's 8*7 / 2 since the permutations "shards x, y" and "shards y, x" are the same as far as fault-tolerance is concerned.
