According to a comment elsewhere on this page, the PAC-3 interceptor has a 19/22 (= 86%) success rate in tests. But in the article we are commenting on right now, they fired 5 interceptors at the target, and apparently all of them missed! The article hints that the issue might have been that the system misclassified the targets and hit the booster instead of the warhead. The moral is that you can't be sure that the success rate is independent, there can be systematic errors that affect all of the interceptors at the same time.
