What the article says around this equation
At the bottom in expected-loss terms, though not in ease of prevention, sit over-retrieval dilution and duplicate retrieval . Both are frequent and both are individually cheap to detect and to fix — the first by measuring accuracy as a function of k against a corpus’s own near-miss rate, the second by exact or near-duplicate filtering before the context is assembled — which is exactly why they belong at the bottom of a list ordered by unresolved risk rather than by frequency.
