Hi Jessica, this is because of missing data. Between our second to last statistic and the last statistic there is a difference of X tweets. The algorithm then takes the average per day between those two points, which seems to be 30 in this case. To ensure your data is more accurate you can press "Update stats now" on your page each day.
