I love that full story allows us to see every detail of our site performance, even when we are not in front ourselves! It has been extremely helpful for me personally since it is much easier than searching through analytics data myself (I do this quite often).
There can be some lag time between page changes so if you have many users or heavy traffic going though your website then try using another tool such as Google Analytics instead - which doesn't suffer from these issues at all. We were looking into how people actually use different pages within my ecommerce store but didn'r have access via google insights/analytics etc due to privacy reasons with their API's being used by other companies too, hence why i started working with FULL STORY!!
