Typical use means how well the method works when real people in real life use it, whereas perfect use means how well the method works when it’s used in a clinical trial. Since life isn’t a clinical trial, we recommend paying closer attention to typical use numbers. On the other hand, if your birth control of choice has a lower typical use rate, you can get closer to the perfect use number by learning to use your method correctly and consistently.
