The passage around this formula

State the sample size the claim actually requires. If a system is being represented as safe at a given tail probability, report the number of trials run and compare it explicitly against the n ≈\approx k/qτq_\tau threshold needed to have observed the claimed rate with any precision, rather than letting a comfortable-sounding trial count stand in for a rate that would in fact require orders of magnitude more observations.
