David is there any way to look at past results in a calendar form ? I study visually and when i see numbers that hit i like to look at the calendar and kinda see how they fall. The first thing i thought of is when you look at the history page and see the date pop up as you hover over it. Im kinda thinking along the same line. So if a number is overdue, you can look at the calendar and visually see it.
You could incorporate colors into it like you are currently with pair sums. So say you pull down a tab and then see the calendar version of a pair sum and when it hit last etc. Just a thought.
