Why can't I see ACX audiobook sales data on the homepage reports?

To see audiobook sales on the homepage/main report you need to be viewing the yearly view (i.e. "Last Year" or "This Year"). All other ACX data can be seen on the Audiobooks page "Charts" tab. This is the case because ACX provides us no daily data which is incompatible with how our system currently works. If we broke the ACX data down by the day then it would show as an averaged daily amount which is inaccurate and confusing. For instance if you sold $100 in July and we took our best guess on date ranges like "Today" or "Yesterday" or July 3 - July 10, we'd have to assign every day $3.23 ($100/31 days in July=$3.23). We decided to stick with annual revenue on the homepage and provide audiobooks their own reporting section until we can offer a better solution or ACX provides more data in their reports.
