Sorry, but cumulative metrics (which is what total user sessions are) aren't very useful. To quote from http://a16z.com/2015/08/21/16-metrics/ http://a16z.com/2015/08/21/16-metrics/ : "Cumulative charts by definition always go up and to the right for any business that is showing any kind of activity. But they are not a valid measure of growth — they can go up-and-to-the-right even when a business is shrinking. Thus, the metric is not a useful indicator of a company’s health." The more useful metrics are over a time period - like the sessions per month one. Looking at percentage growth over time for a cumulative metric seems pretty meaningless actually - among other reasons, it can never be negative even if your business just tanked. Monthly Growth usually refers to the growth in a monthly metric per month, and would be 0% in your case.
