What the article says around this equation
One. Vendor system cards and agent-benchmark leaderboards will increasingly report an explicit reliability statistic — a pass ^k -style figure or a confidence interval — alongside a headline pass@1 or pass@k number, because the gap between the two is now well documented rather than speculative. Disconfirmed if major leaderboards in 2029 still report a single unqualified success rate with no repeated-trial or uncertainty disclosure.
