The passage around this formula
I call the proposed quantity group-valued record redundancy . For accuracy and failure probability , it counts the largest number of disjoint environment fragments from which covariant measurements can independently estimate the same relational orientation within , with failure no greater than . “Covariant” means a change of reference frame rotates the state, the measurement outcomes, and the reported estimate together; it cannot change whether the estimate was successful.
