Okay, I finally looked up Levy's arcsine rule and sort of understand this.
Some trivial notes are that you can remove the "1 s if you start with the 
transpose, and also you should use ?...@$, giving
'#'{.~"0->:-:_80{.\ /:~ +/ 0<(+ 0,}:) +/\ -.+: 156 4000 ?...@$ 2

By the way, what is the (+ 0,}:) for?

I think this works similarly for the version that is supposed to be better, but 
I haven't checked it.

Better send this to programming, because that's what it is.
