Hi Jeremy - right now the Conversion Rate Chart is rolling to show the last 30-days only, the data itself (the raw visitors, views, and conversion numbers) will update continuously and show you either the data for all time or the data since the last time the stats were reset.

Our Dev team is focusing on some other, larger projects right now (responsive design, improved spam filtering, and global scripts), but improving the leads and stats views is on our road map for the future as well.
