The 10-minute interval schedule was chosen through analysis not convenience. At 10 minutes the coalition obtains 6 observations during the 60-minute Model B window — enough to detect a release within approximately 10 minutes of occurrence. Shorter intervals would increase temporal precision but reduce statistical independence. Longer intervals would improve independence but risk missing brief release windows. The 10-minute interval represents an optimal trade-off informed by the expected characteristics of automated quarantine systems.
