A Project Assistant has the responsibility of coming UP with a time estimate for a Work Package. The WP has 3 serial activities each 5 days in duration. An estimator is performing the duration for the WP and is nervous about the WP duration being too short, so the estimator increases the "most likely" activity durations by 23%, and sends it to the Project Assistant. The assistant decides to add an additional 2 days to the WP estimate received, because they want to make sure enough time is allocated in the WP to get all the activities done. The revised estimate is forwarded to the PM who adds yet anothgy 2 days. By what % does the final WP estimate exceed the "most likely" estimate?
