The estimator pool is how the framework keeps any one party from setting the numbers that money and rules depend on: the floor measure, the supply, care, and formation gaps, sustainable output, and the concentration and circulation measures.
Any body that meets published standards of method, openness, and independence may join. Estimators are paid a base fee for every accredited estimate and a reward for accuracy confirmed later, never for agreeing with the others. Each cycle a counted set is drawn at random, with a required mix of kinds and at least five independent estimates; the median sets the figure. One controlling group counts as one estimator, no funder may supply more than a set share of any estimator’s budget, correlated estimators count as one, and a separate accreditor judges method only.
