Back to it. Found `(u⍸t){+/⍵}⌸x` in the docs as an interesting idiom... I guess I'll put off using `⊆`, because it seems like this way of using `key` is better.
It also means I don't need to `grade` anymore, this way.
It however seems as if I''ll still have to "pad" the keys and value, and remove `1` from the tally when replicating.
